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.

While it is exciting, I can see both sides of the argument here. The infrastructure here in the US is built around cars so it would be much less effort to automate the existing infrastructure. On the other hand, things could be so much more efficient if we focused on trains and other public transport that excels at transporting a large amount of people. But that would take so much more effort and money to update the infrastructure.
