One really clever way of doing this that I've seen is to have a very
high res, high speed camera pointed straight down at the ground. By
analyzing the movement of the ground relative to the car, one can
determine the exact path travelled. Hardware's not tough, but the
software would be.
I forget where I first saw this technique. In some car or racing
magazine, I'm sure...
