Or, do something like an item that when you go through/on it, it would give you faster speed, better turning, more hp. The genaric racing power-up setup.
I would like an add-on that makes it so you can use things on it to make it faster, have more endurance, etc. This could make races more exciting.
If anyone feels like doing this, make it so you have to have credits to buy stuff. Such as an admin holding a race, one guy wins so the admin awards the winner with like 5 credits or something which he can use to mod his car.
