I think about this often. I imagine self-driving cars built on 30 year old tech in which the road drives the car via curbside sensors (much easier problem to solve). I daydream about service reps walking through bumper-to-bumper traffic handing out coupons and apologizing for the unexpected delays.

Pay to drive the premium roads when you’re in a rush, or take the discount lanes with advertising printed along the roadway.

We could have quiet, porous asphalt with better water absorbtion. So many fantasies, I digress.
