What Car Sport Belongs In The Winter Olympics?

The Winter Olympics already involves people competing on vehicles constructed by car companies. Why not go whole hog and start racing cars?

I propose Finnish Crosskart racing. You have a set car that's fast (o-60 in 3.5 seconds) not prohibitively expensive (it runs a bike engine) and it follows a strict formula, like with bobsleds.

The focus would be on driver skill, and on a tight snow course, it would look awesome.

What sport, whether it's real or one you just thought up, belongs in the Winter Olympics?
