I love motorcyles and motorcycle-commuted for years, and yes—it sure beats driving a car. But it's not a counterexample here! There is no comparison to walking or biking, especially to work. As I said above, the effect is astonishing.
If I'm walking or biking somewhere, especially anywhere work-related, it feels so damn good. If I know that in the past I'd have been doing it in a car, it feels twice as good. If I see lots of other people in cars trying to do the same thing, I have the moral problem of trying to control my schadenfreude.
The one exception I'd make for automated vehicles, but it's only a partial exception, is trains. As someone once quoted on HN: "Everybody hates buses and everybody loves trains." Trains don't have the quality of walking or bicycling, but they have some other lesser quality that still feels pretty good. Well, maybe motorcycles and trains are tied for second. :)
