Well, we're not. There's a reason you don't see New York City jumping to adopt this tech, and it's because they bothered to invest in a public transit system that makes cars obsolete for a lot of people. If we got decent public transit in more cities combined with an actually functional high speed rail system in this country, you'd see cars become obsolete for a whole lot more people.

This "lifestyle/culture" developed out of sheer necessity given the geographic size of this country and the complete failure to invest in mass transit. It can and must be changed, if we want our future to be viable at all.
