Yeah you have to draw the line somewhere. I grew up in a town of a few thousand people, 45m drive from the nearest "city."

With that population density it's never going to make sense to put something like light rail on that route. So these people will continue to use cars. And that's fine.. hopefully cars continue to get safer and easier on the environment.

I think it's the urban/suburban sprawls akin to LA that really could benefit from better transit/walkability.
