This is actually a perfect use case for a car controlling itself. Automatically applying emergency brakes is something cars (not just self driving cars) have been doing for a while now (in higher end cars).

The thing that puts me off a Tesla (other than the owned by a nazi who bought his way into government thing) is that the fatality rate is double the average, and the weird doors that unless you have been explicitly shown the emergency handle, you’re trapped inside after an accident because the normal door opening latch loses power as part of requirements to not electrocute emergency personnel.

The Cybertruck is scarier, because the emergency personnel will struggle to break a window to get you out or use the jaws of life to cut you out on account of the armoured doors and bullet proof windows.
