I'm starting to make the changes you guys mentioned below and it's feeling better already, thanks for the feedback.
I made a few updates yesterday and today to make the game more manageable and fair. So the download link should be the newer build now.
Fun and addicting little game. Little tires, little engines, big brakes = win.
Heads up to anyone that plays this its not remotely done, once you get to the end it just kind of sits there, you can hit pause and restart or go back to the main menu though.
