From the publisher's web site:

"No driving ability needed - only those prepared to plot, scheme, and make bitter enemies of their closest friends will take the road to victory. Only the downright devious will triumph!

Conjure up a spot of wet weather just as your opponent leaves the pit lane with dry weather tires, or cause a failure in their pit crew's equipment. Increase your chances with a craftily-placed oil spill, or decide to give the leading driver a puncture as they near the finish line.
This is no ordinary race... this is a Really Nasty race!"
