full of concept cars. often outlandish ideas as to how we're going to be travelling on roads in future. maybe that'll 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. now, i'm 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. this is a tesla, which is already fitted with a system that's in most new cars, which uses cameras and radars to hopefully prevent it from hitting something if an accident�*s likely to happen. but what are its limitations? suspenseful music this feels horrible. you so just want it to stop if it gets really close... and it has quite a jolt, obviously, but we haven't hit the child. whereas the tesla... suspenseful music that was quite something. this technology is already being 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 is a general assumption right now that automatic emergency braking or collision avoidance systems that solve problem on cars. but the reality is actually quite the opposite. you know, people still get into car accidents all the time, and this is despite, you know, now, the substantial majority of new vehicles being produced with assisted driving capabilities, the reality is that 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 that data, feeding what it finds into the control software that tells the car how and where to stop. and because it's 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 sort of 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 just take a passenger from point a to point b in a right—hailing robotaxi—like environment. but the thing is, is that 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 in 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 87mph. 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. 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, from the kindles, it's very low energy, it's sunlight readable and it's just colour change, there's no light, there's no leds, there's no backlight there's no 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's bi—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's cold, it'll be black, or you can have a light sensor so it changes colour at night time. 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's very keen to show off its supercomputer. it's capable of high—quality mobile gaming and even has vr connectivity, not that that's much use to the driver whilst driving. its power also means it could be very productive for work on the go. this car isn'tjust about the supercomputer, though. it's also covered in cameras. on the outside, there's one up front and back. internally, there are three as well. and if you're so inclined, you could post yourjourney 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's news or social—related, and with our product, you know, when you talk influencers, of course they get really excited because for the first time, they can real—time at any time in their day or movements 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, you know, that type of information and for those of us, you know, thinking about using the same type of hardware for our families, being able to document those moments in the car with the kids when they're 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, well, this camera probably does beat the usual mirror. so, whilst 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. 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. now, you know area 51 is near here, and it's kind of weird. yeah. well, there is now area15, which is also all kinds of strange, and we sent chris fox to 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, 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. 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 i 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's like an open—world video game and we're going to reward your exploration and play. there's a lot of opportunities here to take a good instagram photo. how much of the design was based around making something like this instagrammable? yeah, social media's massive for us because, obviously, there's all of the posts that — the user—generated content that people provide. i mean, we're full ofjust jaw—dropping art, you know, throughout the 52,000 square feet of this exhibition. but really, that's just scratching the surface. 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, you know, we have everything from digital creators, sculptors, painters, experiential artists all working together to create, you know, 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 fox. that looked right up your street. absolutely was. i love weird and wonderful stuff. give me a weird supermarket, i'm all over it. should we go now? sure. all right. ok, that's it for the short version of this week's click. the full—length is waiting for you right now on iplayer. and, as ever, you can find the team on social media, on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching. we'll see you soon. bye— bye. hello, there. expect a quiet week of january weather ahead. that basically means this high pressure continues to dominate the story. we will see a good deal of dry weather in the forecast, but unfortunately, that comes at a price at this time of year with some frost and fog — and some of that may well linger and have an impact on the feel of the weather. we've still got this weak weather front to sink its way south and east so, during the next few hours, we will continue to see a fair amount of cloud, perhaps across east anglia and southeast england, but that will ease away. skies continue to clear as the breeze falls light, those temperatures will fall away as well, but perhaps not quite as much fog first thing tomorrow morning, temperatures down to —2 celsius. a bit more of a westerly feed, bringing more moisture in off the atlantic, keeping those temperatures up to the northwest of the great glen. but high pressure is establishing itself, keeping things largely fine and quiet. not that many isobars on the chart — so light winds, lots of clear skies, lots of sparkling winter sunshine to look out for on monday. even some sunshine into northern ireland and eastern scotland, just the far north and west, seeing more cloud and thick enough for a little spot or two of drizzle. temperatures quite widely between 8—9 celsius — pretty much where they should be, really, for the time of year. now, as we move into monday evening, we will start to see some fog forming under clear skies and light winds across england and wales, and some of that could be quite dense in places. again, more of a breeze into the far northwest, so temperatures holding up at around 5—6 celsius — but in towns and city centres under those clear skies, expect those temperatures just to fall below freezing. so, a frosty and foggy start as we go into tuesday. weather fronts trying to push their way in from the north and west as we go through the day, but they will take their time in doing so. the fog just confining itself into central and southern england on tuesday slowly, hopefully lifting away more showery outbreaks of rain, moving their way across scotland with those weather fronts pushing in. they will continue to sink their way steadily south. more of a breeze in scotland as well with those fronts. that means potentially, there'll be less chance of fog forming towards the end of the week. but it stays largely fine and dry, and there will be glimpses of sunshine from time to time. that's it — whatever you're doing, enjoy. welcome to newsday, reporting live from singapore, i'm karishma vaswani. the headlines... the man who took four people hostage at a synagogue in texas is confirmed to be a 44—year—old british citizen. novak djokovic has been deported from australia, afterjudges rejected the unvaccinated tennis star's appeal to stay in the country. surveillance flights prepare to head to the pacific island nation of tonga —— to assess the damage caused by a volcanic eruption and tsunami. the uk's opposition labour leader sir keir starmer says borisjohnson broke the law and should resign, over a series of parties at downing street during coronavirus restrictions.
