Driving around so much it's scary

It's kind of scary that I use my car a lot to get around. Had to run a lot of errands today, among them was to get my oil changed. I hate what would happen if my car crapped out on me and I couldn't get it replaced. There's going to be a lot of traffic at this time of year, considering that Thanksgiving is around the corner. Us Americans can be so dependent on our cars that it's not funny, too bad the public transportation isn't more accessible, especially in the Philly area.
