It's not "car owners" in general. It's car owners who behave badly - car owners who want to speed through residential neighborhoods and busy commercial districts, who want to run red lights and stop signs, who don't use their blinkers, who cut people off, who make illegal turns, who drive aggressively or otherwise drive badly, who double park or otherwise park illegally, who don't pay any of their bills and fines, who are the cause of congestion, and so on. And I'd wager a big percentage of the drivers are just doing what they do as creatures of habit. I'd wager a big percentage of them never actually tried alternatives, like park and ride on metro, didn't try to get their workplace to do telework, or anything else.
