I'm not surprised about Los Angeles! I hated it there. Traffic, traffic, traffic nonstop everywhere. San Diego was much better.
New York City - I don't think that New York City is made for driving at all. The city has one of the best subway system and it is so easy to get to anywhere. So, I would rather use the subway all day long and avoid traffic.
Philadelphia is not that bad. I usually drive to a Park-n-Ride and take a train into the city. Then I can walk everywhere in that city because it is a very compact city. Rush hours are terrible in Philly, but at other times, it's pretty easy to move through.
