This is pure projection: I was pointing out that millions of people's daily life contradicted the absolute statement you made. If you'd said “doesn't work for many people” I would have agreed: it's no secret that the U.S. has heavily subsidized car-centric design for the last century and there are many people living in neighborhoods which don't even have sidewalks, much less transit or bike paths.

This has also encouraged many people to think that they must drive even if it's not a great choice: in the city I live in, it's not uncommon for people to cling to the habits they acquired growing up and trying to drive everywhere even though it means they're paying considerably more to sit in traffic while their friends who biked or took the train wonder why they're late.

There isn't a single answer here but the important thing is remembering that these are choices. Giving private car owners exclusive use of public land might be a popular choice but it's not a law of nature, and when it doesn't work well it's reasonable to question whether it's the right design for the context. There's no reason to think that the same answers will be true in rural areas, suburbs, and dense urban cores.
