Earlier quoted context omitted.
I guess one has to balance the time spent in traffic and being crammed with others in public transport. Here in the bay area, one can get stuck on 101 for 2 hours when it would take only 40 minutes via Caltrain. I'm sure quite a few people would rather save 1.5 hours every day being crammed in with others.
Well, 40 minutes not counting getting to the train, waiting for the train, exiting the station, getting to your car & driving from the station home.
On a side note, BART is probably going on strike this week, which means that an hour BART commute is soon going to turn into a 4 hour commute when the traffic on the highways double.
