>Socializing healthcare isn’t going to get an huge portion of the population out of their cars and get them walking as a primary or secondary mode of transportation
You would think so but once healthcare cost becomes a government policy issue people complain about its spending and they are forced to try and bring that cost down. One of the ways they did that in my country was to promote biking to work and build bike ways.
Did I mention the 100° summers or the fact that people usually live 20+ miles from where they work?
I agree with you generally on the incentives, but it took us 70 years to paint ourselves into this corner, and we’re not going to get out of it because of a third-order incentive.
