afterjudges rejected the unvaccinated tennis star's appeal to stay in the country on public health grounds. the on public health grounds. orders of the court are — the the orders of the court are — one, the amended application be dismissed with costs. disappointment and dismay from supporters in melbourne. djokovic himself says he is "extremely disappointed" but will co—operate fully. tennis australia said it respects the court's decision. labour leader, sir keir starmer, says borisjohnson broke the law and should resign over a series of parties at downing street during coronavirus restrictions. the conservative party chairman, oliver dowden, says the culture in downing street must be addressed. i think the facts speak for themselves. i think the prime minister broke the law. i think he then lied about what had happened. people feel angry about what's been going on in downing street, i feel angry about what's going on in downing street but the correct process now is to get to the full facts. australia and new zealand are sending surveillance flights to tonga after a tsunami triggered by an underwater volcanic eruption caused significant damage to the island nation. now on bbc news, it's time for click. this week, we're on wheels as we race through the new car tech in las vegas, and then bring it safely to a stop. but is anyone actually in the driving seat? plus, what's up with this shop? we are at the supermarket that has something very strange in store for you. hey, welcome back to the consumer electronics show in vegas. we have cars for you this week, lots of them. one of the biggest draws at the show in recent years has been the motor hall — so lara, are you ready to get your driving shoes on? i am revved up and ready. ok, so on your marks, get set and go! lara: every year, ces is full of concept cars. often outlandish ideas as to how we're going to be travelling on roads in future. maybe that will be having a chat to your vehicle... do you like it? yes. sounds good. ..or turning the back into a really impractical and uncomfortable living room. this year, though, there was at least one idea with a somewhat more convincing purpose. what i'm filming here is a concept that hopes to be able to create uncrashable cars. i am getting in this vehicle which is embedded with lidar sensors, which should stop it from hitting the luckily pretend child at the end of this track. beside me is a tesla which is already fitted with a system that is in most new cars which uses cameras and radar to hopefully prevent it from hitting something if an accident is likely to happen. but there is limitations. this feels horrible. you so just want it to stop. it gets really close. and it has quite a jolt, obviously, but we haven't hit the child. whereas the tesla... that was quite something. this technology has already been built into cars right now as a safety function, and in the future could be used in autonomous vehicles too. this tesla and other cars with current collision avoidance systems have their limits as to what they can prevent. accidents still happen, but lidar has the potential to raise the bar — even in low light. there's a general assumption right now that automatic emergency braking or collision avoidance systems are a solved problem on cars. but the reality is the opposite, people still get into car accidents all the time, and this is despite now the substantial majority of new vehicles being produced with assisted driving capabilities. the reality is, you would think it would be easy to build system that willjust prevent you from hitting the thing right in front of you, but that's simply not the case with these existing camera and radar systems. luminar�*s laser sensing technology measures how far away objects are, perception software interpreting the data, feeding what it finds into the control software that tells the car how and where to stop. and because it is using lidar, should also workjust as well in low light. you take a look at most of the autonomous vehicle companies that have been out there. they have generally been stuck in this r&d mode, you have these giant roof racks full of sensing systems and a supercomputer in the trunk that's there to run the thing, where the objective is to try to replace the driver altogether, and take a passengerfrom point a to point b in a ride—hailing robo—taxi—like environment. but the thing is what we're doing is not about that, it's about actually making the drivers better, giving them almost superhuman capabilities to be able to actually save lives and have something that has an opportunity to do this today, as opposed to decades from now. and another thing many drivers might like right now is an electric car with better range. well, mercedes unveiled the vision eqxx, a concept car capable of up to 648 miles on a single charge. that could take you from berlin to paris. it says that it's made possible due to a higher density battery, lower weight, 117 solar panels on the roof and better aerodynamics. it took a bit of work then! of course, it will be up to others to certify the range estimate independently, and those extra miles mean there are some compromises, with a top speed of only around 87 mph. not that you should be driving any faster anyway! this particular model won't be going on sale, but mercedes say that many of the features are going to be added to their future evs from 2024 or 2025. meanwhile, here's something that caused its fair share of attention. this bmw changes colour! it's a colour changing car! and to do so, it uses e—ink, the same as an e—reader. what we have here is the world's first real colour—changing car. the technology e—ink is amazing. we know it from the e—readers and kindle, it's very low energy, its sunlight readable and it's just colour change, there is no light or led backlight or oleds, it isjust colour change. so you just need a little bit of energy to change colour, and absolutely no energy to hold it, so it is stable and as an engineer that's a wonderful property to have. the driver can manually choose to change colour, or you can do it via the sensors that are embedded in the vehicle — so you can have a temperature sensor that when it's hot the car will be white, and when it is cold it will be black, or you can have a light sensor which changes colour at night time. why would anyone want a colour changing car? it's a really good question. and aside from the obvious cosmetic aspects and the coolness aspects, which is the first thing that people kind of comment on when they come in, we see self—expression as something important, you know? it's like you choose your clothes, you choose your car, the ability to show yourself with your vehicle is a nice feature. but in addition to that, we can show useful information — so in europe, car sharing is very big and there are a lot of car sharing cars on the street, and to see if a car is free or if it is charged — you would usually have to whip out your phone and take down your mask and put your face recognition on and get the right app, and there are a bunch of steps to take — we think it's beneficial if you can just look at the car and you know it's free, or you look at the car and know it is charged, or you know, have all kinds of useful information on the side of the car. so there could be an actual purpose, apart from driving around wrapped in a copy of war and peace. and finally, here's a car that wants to use its power to post on social media. this is the indi one, and it is very keen to show off its supercomputer. it's capable of high quality mobile gaming and even has vr connectivity — not that that is much use to the driver while driving. its power also means it can be very productive for work on the go. this car isn'tjust about the supercomputer, though. it is also covered in cameras. on the outside there is one at the front and back. internally, there are three as well. and if you are so inclined, you could post your journey on social media. yes, if getting from a to b is an interruption to your constant posting, or the thing you actually want to share is yourjourney, then this car has the solution. from the social media side, it's interesting now because so much of our life is shaped by instant media, whether it is news or social—related, and with our product, you know, when you talk to influencers they get really excited, because for the first time, they can real—time, at any time in their day or movement through the city in their vehicle, they can basically treat their vehicle as an extension of their mobile phone or their home pc. but also, the idea of archiving that type of information, and for those of us, you know, thinking about using the same type of hardware for ourfamilies, being able to document those moments in the car with the kids when they are learning to sing their first songs or the family singalongs or even discussions with the teenagers in the car. i'm sure they'd love that! but for looking at a baby in the back, this camera probably does beat the usual mirror. so while every feature on every car, clearly won't be for everyone, at least there are plenty of new ideas out there to make our roads safer and smoother. and to get us noticed if we want to be. spencer: meanwhile, in a galaxy not too far away, i'm waiting for another ride with a difference. lara: don't tell me, a self-driving taxi ordered by an app? _ actually, no, not quite! not this time. this is not an autonomous car. it is being driven remotely by bill reeves, from the comfort of the headquarters of halo in las vegas. bill's setup is almost indistinguishable from a video game. he is using standard game controllers and a fancy monitor. but the view he sees is not computer—generated. the car he is driving is actually real, and the passenger he is tasked with picking up is actually me. the next surprise is that i am not being driven, i am driving myself now. and the pitch is that while we wait for a world full of autonomous cars which are driving around, picking people up, taking them where they want to go and dropping them off and going off to do other jobs, remote—controlled cars can do some of that work. and that means that some people may not need to own a car. ok, i'm here. the halo headquarters are less plush offices and more a rented house on a quiet street, very much like the start—up pads you find all over silicon valley, where companies live and work together. now remote—controlled cars are not legal everywhere, obviously, but nevada is one of the states that famously allow testing of this kind of technology. which means bill is one of the very few people who have driven a car without being in the driving seat. what does it feel like driving the car that you are not in? it's a very interesting experience. you're missing the road feel. you lose some of the tactile environment sitting here, not in the car. but the camera system is actually better than if you are sitting in the car, so where we have placed the cameras actually gives you, if you are pulling up to an intersection, so we can see around corners actually better with this console than we can sitting in the car ourselves. and you pull up to those intersections when you are like leaning forward, trying to look around the corner? we can see those. everything is right there, so i don't have to twist my head or move, everything happens very quickly because your eye movement is much faster than your head movement. do you feel the added pressure and responsibility of, you are not in the car so if you put it in a ditch, you are not going to get hurt, but at the same time, does that make you feel more removed from the situation and also more responsible for what happens? i think more responsible is what i feel, because you really want to make sure you are the best of the best, right? you want to be the guy that makes all of the right decisions and makes all of the right turns, because you are representing the company in this fashion. now, as i said, the vision here is to persuade some people that they don't need to own a car — they can just call one when they need it. when you buy a car, it is parked 96% of the time. we barely drive it. you drive about one hour a day and 23 hours it is sitting in the parking lot. why notjust remotely drive the passenger when they are in there? why give them thatjob? number one is liability for us, right? when a customer is inside, we need to make sure the ride experience is extremely smooth and the pilot has to always be engaged in the car. now, that pilot, if we take them out and let the customer drive, the pilot can now transition to a different vehicle to move that car. so one more pilot can now manage multiple cars in the fleet. so there is a big clue on the bonnet as to what network you may be using to connect bill to the car. do you need 56? do you need that kind of low latency and high—speed connection? having 56 gives us the latency that we require to make a smooth experience. but to be honest, 56 is not deployed all over the world yet, so we make sure our cars work on lte. now, i've used ag and it's not always reliable, it's not always fast enough to stream video, let alone control a car. it does not sound safe enough to drive a car over any mobile network. absolutely. one of the secret sauces that we have engineered and patented product that we've built... love a secret sauce. we all do — is the ability for us to switch into multiple networks and carriers. so we piggyback off multiple networks to make sure every single packet, or data packet, that comes from all of the cameras that we have in the car gets to the destination. halo will initially target urban areas with very good mobile coverage, but if the signal does drop out anand tells me the car is programmed to come to a stop, diagnose the problem and call someone else if necessary. and, as if to prove how well the car can perform, last friday, bill got to take the halo car for a more extreme lap or two, as it became the pace car at a pretty unusual race. it is really a cool experience to go around the racetrack, you're kind of by yourself so some of the obstacles we run into and we're worried about in the urban environment are not on truck. we just have to worry about hitting the wall! spen laughs so it's going to be like a video game, you've got the video game controller, if you put it into the wall, nobody gets hurt but you don't get a second life? you don't get a new car. no, that's — well, i have to fix the car — so i definitely don't want to hit the wall. laughter a unique pace carfor a unique event at the las vegas motor speedway, where we'lljoin richard taylor in the pit lane in a couple of minutes. hello, hope you are ok today and welcome to the week in tech. it was the week over 80 groups signed an open letter to youtube asking it to improve its response to disinformation. the co—founder of now meta—owned whatsapp is taking over as the new ceo of rival messaging app signal. and france has birthed a unicorn in the form of backmarket. the company, which sells refurbished devices, was valued at 5.1 billion euros. staying with the fixing theme, in a bold move championing the right to repair movement, microsoft have made its own teardown and repair video for its surface laptop se. normally videos like this are made by third—party sites like ifixit — a gentle reminder though, be gentle if you do decide to go down the diy route, and seek advice if you don't feel competent. two los angeles police officers were fired for pursuing a snorlax in pokemon go. court documents show the in—car camera recorded them playing the augmented reality mobile game, instead of responding to a call. though that particular pokemon is relatively rare. and finally, plucky mars rover perseverance ate rather a bit too much over the holidays. nasa jpl said the vehicle gathered a few too many rocks during a routine core sample collection. here's its selfie of those pesky pebbles caught up in the martian machinery. they're trying to fix it as we speak. let's hope perseverance lives up to its name. this is the indy autonomous challenge. the clue�*s in the name — look carefully, you'll see there's no—one at the wheel. instead, these sensor—rich hot rods are essentially entirely preprogrammed supercomputers. each is differentiated only by software custom—designed by nine engineering student teams. this is the million—dollar beast that has been given to each of the teams competing, and course it's chock full with a ton of different technologies. three lidar, three radar, six cameras, gps and bleeding—edge processing. today the teams are making iith—hour tweaks to their algorithms ahead of the final showdown later in the week. the race winners will claim bragging rights and a $150,000 cash prize. in practice though, the teams are incredibly collaborative. they understand there's a far bigger prize at stake for us all as they race ever closer to a driverless future. people are watching us race, and people are watching us do all these races, so i guess in a way you are kind of increasing public trust towards autonomous vehicles. because someone sees hey, this car's travelling at 180mph around a track, with other cars on the track, and avoiding them, maybe they feel more comfortable in getting in an av vehicle and having it drive them from their hotel or their house safely. this is a practice day but on friday what is going to make this race truly groundbreaking is that the teams are gonna be flying around the track, notjust to compete on seeing which car is the fastest, but also if they can pass each other at increasingly higher speeds. passing is incredibly important, because it showcases how autonomous vehicles can perceive one another, can determine when to pass, when to overtake, and we're going to need to do that in regular highway driving if people are in different autonomous vehicles, they're going to have to encounter one another at high speeds. and it's never been tested out, no—one�*s ever done high—speed passing of autonomous vehicles ever in the world, so this is going to be a real first. so, race day is here. the original multi—car head—to—head contest proved a little too ambitious in these covid times, so this is a knockout contest between two cars at a time, each taking it in turns to pass each other safely at high speed, until one car fails to overtake and gets eliminated. and all does not quite go according to plan. ouch — it's going to be a pricey fix. organisers say crashes like this are par for the course, as the tech matures. but won't they also dent consumer confidence? i don't think so. the main advantage of it is trying to develop the technology. if you're able prototype something running at 300 kilometres an hour, then when you are running at urban speed of 30 kilometres an hour, you have a safety margin that allows you to safely adopt these kind of algorithms. finally, after two plus years in the making, it culminates in a few crucial minutes on the track and a winner is declared. so what to do with the prize money? we spend a lot of money to do this, it's very intensive, i had a big research team with phd students, we invest a lot of money, and so it's for research. there's a sense that this is an historic milestone, but also a recognition it's just a waypoint on a far longer journey that lies ahead. eventually we'll get to the point where it's real head—to—head racing with multiple teams. so we're already taking off—the—shelf technology and making it better, and soon those technologies are going to find its way into autonomous vehicles that you and i are going to be riding in in the future. now, having been to vegas every year since the beginning of time, i thought i'd seen everything here. but it turns out there's something new this year. you know area 51 is near here, and it's kind of weird. yeah. well, there is now area 15, which is also all kinds of strange. and we sent chris fox to check it out — check it out — check it out. i've popped out to do a big shop at the most talked—about supermarket in las vegas. i've heard the prices here are to die for... but at this supermarket, nothing is quite as it seems. omega mart looks just like a regular supermarket. they've got food and drink you can actually buy, but everything's been infused with a secret additive—s, and the ceo walter dram hasn't been seen for a while. it makes you think there could be a mystery lying just beneath the surface... x files-like music plays stepping through one of the shop's portals takes you to another dimension where more of the mystery unfolds. but what you do there is up to you. there's a story to immerse yourself in, using one of the store's loyalty cards to track your progress, or you can simply treat it as a very instagrammable multisensory playground. more than 300 artists have worked on creating the experience, with more than a0 projectors providing some of the visuals. in the parallel dimension i met drew dicostanzo, and asked him whether this was more art or escape room. i think it's both of those things and more. it's really whatever you make it. you know, we're not going to tell you how to experience omega mart, what to do, it is like an open world video game, and we're going to reward your explanation and play. ——exploration. there is a lot of opportunity to take a good instagram photo, how much of the design was making something like this instagrammable? social media is massive for us. because obviously there's all of the posts, the user—generated content that people provide. we're full ofjustjaw—dropping art throughout the 52,000 square feet of this exhibition, but really, that's just scratching the surface. you know, as you start to wander and explore these different areas, you'll start to discover there's a story, there's a few different narratives that are happening. there's mysteries to solve. and if you dive even deeper down the rabbit hole, you can go through some rfid progressive digital gameplay that will take you a couple of hours to hack and unlock secrets throughout the entire exhibition. drew, what inspired the omega mart? it's something that started as a small backyard art project, that evolved eventually into this huge project that took three years to create. it took 325 artists from concept to opening, and we have everything from digital creators, sculptors, painters, experiential artists, all working together to create this narrative and build it out. so a really giant process that took a long time. while the traditional high street has struggled in the internet age, the omega mart is thriving, and the company is already planning an expansion to this immersive experience, and opening some others. so the next time you're out shopping, do be on the lookout for any suspicious looking wormholes to another dimension. that was chris — that looked right up your street. absolutely, it's so weird and wonderful and brilliant, give me a weird supermarket and i'm all over it. do you want to come? sure! all right, we'll go, that's it from us from las vegas this week. as ever you can keep up with the team on social media, find us on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching, we'll see you soon. bye— bye. hello. i think a pleasant enough day for most of us in store. there could be a few showers for a time today, but on the whole, we'll focus on the sunny spells. so let's have a look at the big picture across our neck of the woods, and a weather front has been moving into scotland and northern ireland, and this weather front has brought temporarily cloudier conditions in the north, a little bit of rain, but also behind it you can see slightly milder air, which is actually riding around this area of high pressure here. so the milder air has pushed across the uk, hence it wasn't so frosty this morning. and here is the weather front around two o'clock, three o'clock in the afternoon, just a line of cloud across parts of east anglia, the midlands, southern parts of wales, a few spots of rain at most. further north, we've got plenty of sunny weather, but a bit blustery with a few showers there in the northern isles. now tonight the winds fall light. this area of high pressure almost sort of wobbles back across the uk, and a frost to come tonight. temperatures in city centres will be close to freezing across england, wales and northern ireland. again, milder in the north of scotland because of that ocean wind. so the high pressure slap bang over the uk and france on monday, so dominating the weather across many western parts of europe and will stick around for most of the week, and that means that the week ahead will have frosty and foggy mornings, but sunshine during the day. so early on monday, we'll probably have patchy mist and fog across parts of england and wales but, on the whole, it's a sunny start for most of us, and that's how it's going to be through the day. whether you're in the south of the country or the north, i think a fine start to the week. temperatures will be around eight degrees, pretty much across the board. now here's the forecast map for tuesday — high pressure in the south so calm conditions here. but a weather front moving through the northern half of the uk and the north—west here, so some rain, maybe for northern ireland and scotland. but to the south, i think dense fog likely early on tuesday morning across parts of england, particularly east anglia and the south—east. and i think on tuesday a chance of some showers in the north of the country, but staying brighter, sunnier weather, fog clears in the south. so here's the outlook for the week ahead — generally speaking, with high pressure, we are in for a fine, calm and settled week. enjoy the rest of the weekend. good afternoon. novak djokovic has been deported from australia after losing his attempt to have the government's decision
