We have something like that in eu with road markings. Both for clear weather and fog/rain. They mark some of the lines differently, and tell you how many lines you should have between you and the car in front. I think they were first trialed and then printed in several places.

I think a lot of people would just consider that a challenge.

On the occasion when I am towing our travel trailer, it is really incredible how unsafe that makes other drivers act around me. They will jam themselves in front of me at all costs, with no consideration for physics.

There was a bike light that projects a bike lane onto the road, not sure why they are not more popular.

Can't wait to get blinded by lasers when cars are going over bumps and speed humps.

I know you were probably writing tongue in cheek, but that is one of those "solutions" that doesn't stop bad actors and makes good actors more miserable than usual.
