“Mebbe he can stop his cars from turning into portable crematoriums when getting into minor accidents”
Hitting a tree at 90 is not a minor accident!
The report I found said "75-90" according to witnesses, indicating that they really don't know how fast he was going. The road in question is a 6-lane highway, so 75 wouldn't have been unusual. The black box should tell them the speed, if it survived the fire.
But it was still not a minor accident in any event.
But what happened to all the wonderful safety features, like automatic braking, that are supposed to keep the driver out of trouble? And the real question is whether he was on autopilot when it happened, and what caused the car to "swerve through 3 lanes of traffic".
And the fact remains that a fire in a Tesla (or any other similar vehicle) is extremely hard to extinguish. How long was it burning before the police arrived?
