No it’s not. Everyone in America goes to Disney World, which was made by a train nerd and you can’t even drive into the parks. Everyone goes there, rides around the trains and walkable areas, and then goes home to Ohio and drives around in their giant SUV.
It’s not because people don’t know about trains. It’s because they don’t value the things you do, and they value things you don’t, like having distance from strangers and being able to buy a lot of stuff and cart it around with them everywhere.
All my family is immigrants from Bangladesh. They’re not steeped in generations of American car culture. But, for some reason, car culture is the thing they assimilate into most easily. My cousin was living in Queens (where all the recent Bangladeshi immigrants are) and moved to Dallas. She’s thrilled about having all the space for her kids to run around, the apartment with a pool, etc. She doesn’t miss having to schlep her kids on the subway around aggressive homeless people, people singing to themselves, panhandlers, etc.
