Even if we accept that the personal vehicle provides a better experience for an individual in a vacuum compared to ideal public transit, we're left with the critical problem that if a significant number of people choose to use personal vehicles instead of public transit, then there will be so much traffic that the experience will be awful for everyone. This traffic will cause travel delays, noise, pollution (from exhaust, brake dust, tire dust, etc.), and create an unpleasant dangerous environment for pedestrians and cyclists.
