I would like to propose 2 new categories.

1. hit a cow %. It this run you must get over the fence in moo moo farm and hit a cow as quickly as possible.

2. Single course (brake). Driving a course as fast as possible but B must always be held down so that steam is coming from the wheels. (If someone with suitable talent could win all cups while doing this that would also be a fun category, alas I am not sure how feasible that is.)
