As Keith says, the contract is there to stipulate what can and canoot be done. The use of the word "racing" has a legal definition, which is then expanded in the contract by the use of words like "timed events" to cover things like drag racing. Also check the "pizza delivery" clause that's in there too!

A contract works both ways - unless it explicitly states in the contract not to, then you can do it. That's the way laws work.
