New York City does public transit remarkably. I've heard that London, England does as well. In both cases I would take public transit over a car even if the roadways had little congestion.
The top of Upper Manhattan to Brooklyn can be an hour and a half by public transit vs. 45 minutes by car. Queens to Brooklyn can be worse. New York City has transit that is good enough, meaning you don't have to have a car, but it's still atrocious. If you have to do a commute like that, even if you want to use public transit rather than a car, you have to be prepared to give up an extra hour and a half a day roundtrip.
