Unfortunately agree, especially given how much of an influence the auto industry has on our government.
My goal is hence to make enough money to allow my family and I to live in an urban walkable environment. The venn diagram overlap of areas that have a high proportion of large trucks and how livable they are is quite small anyways.
Are there any cities where you don't need to be very wealthy to live there? The four you mentioned do not strike me as the kind of places you can live in without significant resources (I'm an Australian; I've been to all those cities except Boulder and wouldn't fancy living somewhere in them that was walkable without a lot of money, but I don't know them extremely well).
