That’s not how crash tests work. To be able to get the vehicle certified, they drive the car into concrete barriers at a variety of angles and evaluate dummies for injuries. If the injuries are too severe, then the car will fail. In addition, there must be mitigations in place for what happens to wheels/engines in a crash scenario. If the engine immediately gets flung out of the engine bay, it will fail. Yes, I understand this is an electric vehicle.

In reality, modern cars are extremely safe (as much as a 2 ton hunk of metal can be).

Now, this calculation may be different for other vehicles involved in an accident with a cybertruck, but in reality, a concrete barrier is much harder than even this ugly slab of steel. The other cars are also engineered to absorb the same impacts.

Arguably the most vulnerable party in a cybertruck accident is a civilian located outside of a vehicle.
