A similar issue is street sizes in the US are much larger than in countries with good transit and walkability. Anecdotal, but compare image searches for "American Street" and "Japanese Street". Not only is the driving area of the streets much narrower, on street parking doesn't really exists in Japanese cities. This contributes alot to the walking experience.

Of course, auto safety standards that worry only about the occupants of the vehicle, and not whoever they hit, don't help either.

People say to me "but it takes 90 minutes to go 15 miles on transit!!" - the problem isn't that transit should be faster, it's that you shouldn't have to go through 15 miles of primarily asphalt hellscape to get to basic amenities!
The core of Dublin is less than two miles across. I used to live in the middle of it and never missed a car. The core of San Diego.. well it's not really a core, and even then it's routine to have to travel several miles for basic errands, even if you live fairly close to downtown. A downtown that is prevernted from growing by parking minimums. Of course, if you ask a potential employer about transit access they look at you like you're from Mars (and, of course, choose to move on to a less hippie-ish applicant)
