You know, I just thought of another giant flaw in the magnetic bumpers concept:
For every repulsive interaction, there is going to be an attractive interaction somewhere else.
Say you give all cars powerful N-poles on their front and rear bumpers. Great. All cars repel each other as long as they are oriented bumper-to-bumper.
But those magnets also have S-poles. One car approaching another from the side will actually be attracted, worsening side-impact accidents!
