For you the whole world is just a game and you don't care if you did some bad stuff to other people. As long as you are happy with what you have done then you won't regret anything. It the adrenaline rush that you are after and you can't get that if you would drive carefully.
Drive your car as fast as you can till you reach the finish line. Grab as many coins as you can since you can use that later to upgrade your car. Don't forget to use your booster, so you can get more momentum on your side.
