My car is a smart car. It can't talk to me and tell me when to turn left or anything like that. It does tell me when I need to get new tires. A combination of my NASCAR style driving and forgetting to rotate my tires leads to slighty worn front tires. When I drive with less than optimal tires, my car somehow picks up static electricity from the road. So every time I get out of my car, I get a little zap. It's the Camry's way of telling me it wants new shoes. Of course, unlike Jeff Gordon, it takes me more than 15 seconds to get a 4 wheel change.
