HOT TAKE OF THE DAY bicycles are not cars. When you get into a car you suddenly need a hundred times the road space of a person on a bike, you can’t see around you very well, and you can’t hear anything.
But cars exist to move people; that is the economic justification for all we do for these machines. Until we focus on the real reason cars (and bicycles and scooters and sidewalks) exist, we will pour staggering amounts of money into a deadly, ugly system that only serves upper socioeconomic classes. And even them, not very well.
As I track the handling of traffic issues in my town the one core principle driving every solution is that there must never be any interference in the flow of “traffic,” by which they mean cars.
