As Bedford points out, the opposite is also true:
"A good sustainability and quality of life indicator: the average amount of time spent in a car."
(Elevated time car-commuting time also turns out to be a reliable metric of social isolation and general life dissatisfaction.)
@straphanger I can attest that this is true for me since my mobility is mainly walking or biking. But almost all of the people around me seem fine with the auto thing. When I do drive, however, I am more sensitive to how horrible it is, even without congestion.
