I imagine that it has to do with the age of those cities. They were established before cars, so the older parts were designed to get around easier. At least that’s what I assume, because virtually all the cities with low car ownership are in New England.
The title could be cities with good vs bad city planning. All the green cities are designed to force people to use cars, because they made everything so spread out with little to no public transportation. The red cities are built properly with public transportation to help people get around.
Yeah, I went on a road trip a long time ago. I remember it was almost all highway with tons of cars without a good public transport system. They knew they were growing and could have held off the heavy traffic with commuter trains and a substantial public transport system.
Sure there’s a system already in place in LA, though I’m sure there’s room for improvement.
