from what i've seen so far, yes, i would have to agree. maybe you should try after 12. we may be 3,000 miles from beijing, but residents likejoanne are trying to weather a storm in china's property sector. she wants to get out of forest city. and as night started to fall, i met someone who already had. i feel freedom, to be honest. i feel free. i finally escaped this multi—billion project. it's supposed to be good. it's supposed to meet expectations, but it's frustrating. the property developer country garden sold this place as a thriving eco—friendly community, with beaches, bars, restaurants. it was a chance for chinese investors to own a second home abroad and then rent it out to locals. but as we've already seen all over china, ambition didn't match reality. chinese government controls on how much companies could borrow and how much chinese citizens could spend on foreign property have left forest city in disarray. this place was supposed to be a restaurant. i think behind me, judging by the looks of things, it was supposed to be the kitchen. country garden's slogan for this whole place was "a prime vision for future cities". but if you just take a look around, it doesn't seem that way. country garden insists that the project will be finished. but with the company facing debts of nearly $200 billion, it's hard to see how. forest city was supposed to house a million people. right now, it's 1% occupied. like so many chinese property developments, this place seems to be going nowhere. bbc news contacted country garden group in china and received no response. its malaysian operation did respond and said that... a former technician at the electric car—maker tesla has told the bbc that he thinks its assisted—driving technology — known as autopilot — is unsafe. lukasz krupski is in the uk to receive an award for deciding to blow the whistle at tesla. he leaked internal memos allegedly detailing the safety issues. the company, which is led by the controversial entrepreneur elon musk, has declined to comment. here's our tech editor zoe kleinman. over—the—air software updates ensure that autopilot gets even better... this is how tesla wants its autopilot software to be seen, assisting a human driver who is ultimately still in control. but when former employee lucasz krupski voiced concerns he felt about safety in his own workplace, and later on with the tech itself, his dream job turned into a nightmare. i became very depressed and anxious. i couldn't sleep. mr krupski was personally praised by tesla owner elon musk after putting out a fire. he claims his managers turned against him when he raised his concerns directly with the tech billionaire. he then told us he found he could easily access a huge trove of sensitive internal company data, ranging from personal staff details to safety information. he chose to hand it over to us regulators and, controversially, the press. i spoke to multiple hr partners, managers, different levels of compliance, and it didn't work. if you don't speak to compliance, what else you can do? the dutch data protection authority, where tesla's european h0 is, are looking into the data breach. some of what mr krupski says he saw continues to alarm him. i found that the car unexpectedly brakes out of nowhere, because it interpreted a shadow as, let's say, some obstacle and needs to suddenly brake. and that can put the car in danger and everyone behind as well. last month, the government announced new proposals for driverless car regulation here in the uk. in san francisco and beijing, you can hire a taxi with no human driver at all. but are we ready for the tech? so it might be relatively easy to get the technology to drive relatively safely on, say, a motorway, which is already quite a controlled environment. it might be next to impossible to get it to drive safely through central london so that we can all be really confident that it causes no additional risk. but that's all a long way away from the hype that's currently coming from the people developing the technology. do you think that tesla autopilot is safe? unfortunately not. i don't think the hardware is ready and the software is ready. so even if you don't have a tesla, your children still walk on the footpath. i have this terrifying feeling that one day a car mightjust harm them. tesla did not respond to our emails. according to its own data, at the end of 2022, us tesla customers using autopilot averaged one crash where the airbag deployed roughly every five million miles traveled. tesla drivers not using it averaged once every 1.5 million miles or so. the us driver overall average was once every 600,000 miles, but we can't independently verify tesla's figures. meanwhile, the first delivery of the car—maker's latest vehicle, the cybertruck, went ahead in the us last week. tesla's boss elon musk continues his push for a driverless future, and the uk aims to be on a similar track. zoe kleinman, bbc news. to hollywood now where members of the screen actors guild in the united states have until later today to decide whether or not to ratify their union's hard—fought deal with studios over pay and conditions. the guild has strongly urged members to back last month's agreement, saying it is a lucrative and innovative package. grievances led to a 16 week strike that cost the industry billions. we were hoping to cross to new york for additional insight but technical gremlins are preventing us from doing so. in other news... technical issues at the london stock exchange have caused delays in trading with a couple of companies. a technical glitch has twice affected the trading of some shares on the london stock exchange today. investors were temporarily unable to buy or sell shares in smaller companies including deliveroo and asos but companies on the major ftse 100 and 250 indices were unaffected. let's speak now to our north america business correspondent erin delmore. is the vote in hollywood likely to pass?
