The only somewhat effective way of countering carbrain is by travelling to different countries, and experiencing decent public transit for the first time. Still, there are people who do see it and are stuck at the idea that it just can’t be implemented in their own country.
I almost lost my mind once when someone was telling me that a train is less scalable than a car. Like dude, do you think paved roads just spontaneously burst out of the ground?
Literally had a conversation with a guy who assumed that all roads were just paved over old ‘naturally made’ wagon trails, and I had to explain to him that for most American parceling, the roads usually came first, then the government parceled the lands, which is why areas without roads are usually unparceled, and that most American cities were created by proximity to either trains, harbors or highways. It genuinely escapes people that you don’t build infrastructure around development, you develop around infrastructure.
