Quite frankly, I think this is very dangerous thinking: We have seen the stuff going on when Lady Di's Mercedes collided with a massive concrete pillar at very high speed. Yes - the people who were buckled up in the car survived the crash but there were questions about the car's safety nonetheless.
Any car will kill its passengers if you only use high enough speeds and hard enough an obstacle. At some point, even if the inside space would still be perfectly in tact, deceleration forces just become too high.
Accidents are always very dangerous and I think no matter what car one drives - don't rely on the safety of the car. I know a piece of s*** driver who told me he needs a safer car since he caused a lot of accidents and needs to make sure he is protected as well as possible. Let's make sure that Tesla's don't become the vehicle of choice for reckless drivers "needing protection" but rather the vehicle of choice for responsible drivers who appreciate a smooth, economic and environmentally friendly ride :smile:
