I've never heard a discussion on quitting cars anywhere offline, to be completely honest.
The amount of people who currently drive cars who think to themselves, "You know what would be better? If I were sitting on some form of public transit right now..." is a very small portion of the real world population I assume (In North America)
Sometimes, the internet is not real life...
You're looking at it backward. I think almost everyone who sits in traffic or nearly gets in a crash by someone doing something stupid thinks, "Driving is awful." They've just been conditioned to think there's no alternative.
