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

  The other car is the crumple zone.

    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?

  the bodies of children it’s software won’t detect will have plenty of crumple zones, don’t see what’s the issue

  the thing is a giant slab of angled metal, when it crashes into things my guess is the hood will slide backwards and “dissect” entire people.

    That’s a threat with most vehicles and is easily engineered for. Aside from visibility problems, we can’t know what real safety issues it might have until we get crash test data.
