Also, if you get hit by a Cybertruck at 55mph, the sharp angles are going to cut you far deeper than a Mini Cooper would. You're not going to walk away from it either way, but you're probably more likely to perish from the Cybertruck.
(That doesn't stop me from wanting a Cybertruck but that's just because it's cool in other ways. I don't know if I'd want one to be my daily driver, but it is very cool.)
It's not perfectly safe. If it were, it would be legal everywhere and it's not.
At 55mph perhaps this doesn't matter, but most vehicle-pedestrian collisions occur at far lower speeds than that, and then it absolutely does matter.
I self identify as a Tesla fanboy, the model Y is the best car in the world in my opinion, but even I have to admit the cybertruck has several fatal flaws and just isn't a good vehicle.
On paper it has a bunch of things going for it, for example it is (as far as I know) the cheapest fully electric vehicle with air suspension. In practice it all falls apart (both literally and figuratively)
I wish Tesla would try again and build a new truck, without the cyber and the cold rolled stainless steel. Stick to the design language of the other Tesla models this time. Let Franz do his thing.
Oh look, another Tesla fanboy using an extreme example to avoid discussing a legitimate concern.
As for pedestrians, cyclists, etc. it doesn't matter if you're hit by a Mini Cooper at 55mph or a Cybertruck at 55mph, you're not walking away from it. But the Cybertruck has far more anti-collision features than almost any production car in the world, along with the entire Tesla line.
