On the street, you can usually count on the steering wheel to point your car where you want it to go. On snow, a high speed race track, or in the dirt there's a lot more physics involved. When I'm not sitting behind a desk blogging about physics you can find me and my son JP out racing through the dirt, mud and snow in JP's 2002 Subaru WRX . He has to drive it to school too, so we do our level best to keep from knocking pieces off during our weekends running with the Sports Car Club of America Rally Cross crowd.
