It was because the device locked them inside.

Tesla programs its devices to do that as soon as they're rolling faster than 5 MPH – for the sake of saaaaaaaaaaaaaaaaaaaaaafety! So when the device crashed, the doors were locked – and so they stayed, apparently because they could not be unlocked on account of them being electrically actuated.

Tesla is not the only manufacturer that does this. It's an example – among the worst – of this intolerable (to any adult who isn't a child) ethos of electric parenting embedded in pretty much every new vehicle. The doors lock as soon as you start driving because it's saaaaaaafer that way. They lock again as soon as you park and get out – also for saaaaaaaaaafety.

Buckle up for saaaaaaaaaaafety! If you don't, the car will "remind" you to do so – implying you'd forgotten to as opposed to choosing not to – until you give up and put the damned thing on. Like a good little boy or girl.

Ding! ding! ding! goes the annoying chime when the car thinks you're about to back up into the bush in your driveway you already know is there – and know from years of experience just exactly how far you can back up before bumping into it. Never mind. The car knows best and will pester you if it thinks you're getting "too close." Some will even forcefully slam on the brakes for you.

This will get worse, soon.

A federal edict will shortly go into effect – unless rescinded by President Trump – that requires  all new vehicles be programmed with automatic emergency braking – a system that is already embedded in pretty much every new vehicle, in anticipation of the requirement. When fully activated – come 2029 – every new car will automatically slam on its brakes whenever it thinks you're too close or following too closely. Expect many rear-enders to ensue. And then expect everyone's insurance to go up (again). It will of course all be blamed on the vehicles that lack this "technology," which will be framed as unsafe and either banned from the roads or effectively banned from the roads via the clever expedient of jacking up the cost to "cover" them such that few will be able to afford the "premiums."
