Hah, I'm the opposite. Despite having pretty great transit here, my needs don't quite line up with the transit network, and so some times are far longer than they are by car, to the point of 20min drive vs 1.5-2hr transit. Given that, I got a car... and now prefer it whenever possible.

If I want to engage my brain at all I'll listen to a podcast or something, but often those half hour periods of relative disengagement are very nice breaks to have.

That said, I do choose 10 minutes of walking over 2 minutes of driving in anything but a torrential downpour, or 2 minutes of walking over an extra 30 seconds hunting a closer parking spot. Maybe it just all comes down to not wanting to deal with (potentially unpleasant) people.
