What you could do if your planning on updating the game is
1) Add a mini map so players will be able to see where the opponents are. This will also tell them how close or how far they are from the closest opponent.
2) What you could do is make themes where players will be able to represent certain countries. If its USA for example, the car could be red white and blue with a few stars. Players
3) You could let players choose the color of their cars.
Pretty good game overall.
