The Tesla truck should fail all pedestrian safety requirements for the Euro NCAP testing to many hard angles and surfaces, getting hit by one of those at chest height and then being dragged under it would ruin your day.
Thats why I think the vehicle they have shown was a complete stunt, as was the bit about armoured glass. I did cynically wonder if he was playing with the share price as it dropped massively following the launch where as I suspect there would have been speculators betting on it going up following the launch. Elon Musk seems to have frequent issues with short term speculators who will have lost out as a result of the share price drop, where as he will recover the share price for long term investors (who he does like) when he presents the real vehicle.
