Driver's Ed

I think I'm a decent driver. I mean, I don't think I deserve an award or anything, but I'm pretty good, above average even. I've never had an accident, though someone did hit my car in the Vanderbilt employee parking garage and didn't leave a note. The Honda still bears the scar. I do get an occasional speeding ticket (3 in 15 years, and one was highly debatable), but I haven't had one in a good while. I wear my seat belt religiously. I really like using my turn signal. I almost always come to complete stops at stop signs. I let people in in traffic. I'm not known for squealing tires. Still lately, whenever I put the car into drive, Pax pipes up in the backseat, "Be careful, Mommy!" What does he know that I don't?
