Learn to drive is the best way to cheat . Your hidden skill will show up on the race track and not underneath that large belly you have that is holding up your pants. I won't tell anyone. I've just read the TCS rules and it doesn't say anything about driving alot to learn how.
I race all the time with other car drivers and they all use different motors and cars. If you keep your TCS set up, you will be come a better driver with all the items that are legal.
