I know a well designed cage would potentially stay intact (smart cars are a good example), but there is no room to dampen the forces applied to the human inside. Even if you can manage to preserve the vehicle frame integrity, the human inside can get pulped. I don’t know if it’s better or worse than a motorcycle in terms of safety during a wreck, but it’s a consideration that would need to be taken if these were to be highway legal.
You’d be surprised at how strong small frames like that can be.
