Comment on Some Tesla engineers secretly started designing a Cybertruck alternative because they 'hated' it

  I wonder how much the other car’s crumple zone affects the performance of your own. I wouldn’t be surprised if one car not having one would degrade the performance of the one that does.

  In which case, these cars actually become a public safety risk.

    The crumple zone absorbs kinetic energy / momentum and allows a smoother and slower deceleration for the passengers as the energy transfer of the impact gets drawn out over time. The suddenness of crashes is what causes the greatest injuries, so you want it to be less sudden.

    If both cars have equally performing crumple zones then both zones contribute equally to this “jerk reduction” (a rapid change in acceleration is called jerk), but if only one has it then you only get half as good reduction and the slowdown will be more sudden.

      I thought that might be the case but I didn’t want to speak authoritatively.

      Yeah this cyber truck is going to make accidents a lot worse.

  So the pedestrians are as well?
