Handicapped people are more affected by the inverse. Small cities are great, car-centric communes are terrible for them. They’ve worked out their own mobility issues, but those solutions are interrupted when the crosswalks and pedestrian bridges are affected. If the “solution” involves getting in and out of a car repeatedly, it’s often cumbersome for people in wheelchairs.

All our old Saturday newspaper comics involve kids going places themselves on foot or bike instead of constantly “being dropped off”.
