Modern cars have softer bodies with deformation zones to save lives in both cars in a collision. With the rigid body and tank like design, the Cyber Truck looks like it could be very dangerous both for its passengers, but even more for the passengers of the other vehicle. If another car hits the Tesla from behind, the angled back looks like it could push the Tesla up on top of the other vehicle. (The front is not much better)
I bet the Tesla engineers have a solution for this. And I really look forward to the crash tests. If they show me it is not built to kill people, I will definitely get one.
