They do (I've seen photos of assistance service cars with a bunch of batteries tacked on in the back), but it's a very new thing and not very common yet. Also the assistance service cars are mostly petrol based still, but even for electric ones I've been told it's non-trivial to wire the existing batteries out (… safety mechanisms and whatnot), making extra battery packs the go-to.

> making extra battery packs the go-to I mean we are not talking about charging the vehicle to full. You only need like a hand portable battery to jump start the low voltage system. The procedure is described in the owner's manual: "In the unlikely event that Model 3 loses electrical power, you cannot access the touchscreen and are therefore unable to release the parking brake without first jump starting (see Jump St…

Is it? What if it runs out of power at 70mph in the middle of a motorway? I’d have thought sudden breaking would have been the most dangerous thing to do

It shouldn't be as emergency stops can be performed at any point in time - usually when there's an emergency. Obviously it's important that following drivers have left enough space so that they can react in time, but that's down to their driving skill (or lack of, if they're too close). I'd consider that autonomous vehicles should apply the brakes if they find themselves in an uncertain situation as reducing speed is…

In New York, sure. In Salisbury? I'm not even sure the fire engines are equipped for that kind of activity, and I'm almost certain the fire service isn't prepared for the liability.

Good point. I really don’t know what the laws would be like there. I just assumed that a fire department would be capable of dragging a sedan and likely immune to liability if they decided it was a public safety issue.

It’s amazing that this is considered “news”. My ex owned a Volvo S40 that had an electric wheel lock that failed in a way that required the car to be dragged onto a flatbed. Car refused to unlock the wheel or switch into neutral gear when the key was inserted. Failures cause cars to be stuck all the time. The issue here was the failed response, not the failed car. Doubly embarrassing that HN thinks this is front page…

It's not 2010. Back in the days this type of error (as well as speed regulator not disengaging...) happened often in low-quality cars. Nowadays, it seems like even 'luxury' cars are low-quality, and Tesla, for better or for worse, started the trend.

That is an unhelpful quote. Yes, some cars have electronic parking brakes. It is quite common on new cars today. But they typically require being affirmatively commanded to change between their applied and unapplied states. Nothing about the general existence of electronic parking brakes explains why this particular vehicle would have one engaged mid-turn.

> Nothing about the general existence of electronic parking brakes explains why this particular vehicle would have one engaged mid-turn. Did you notice the part that it run out of battery mid-turn? It seems that the brakes are designed to fail safe in case of a battery failure. I see how someone could argue for that as a design choice. The fact that there is no way to emergency release them without power is more ques…
