The racing world is serious and if you are not up to the challenge then your competitor will just eat you up. Actually, you will just be the laughing stuff if you are not up to the challenge. Anyway, you would not get paid as you will lose in every race.
In this game, you need to race like there is no tomorrow because if you can't compete then the game will be over. You will not have a problem on the first level since there are no competition there and you can finish the race whenever you want. Grab as much coins as you can since you need those to buy some upgrades.
