Yes I did

Here are the colors
Red, track designed for fast cars
Blue, track designed for any type of car, except it has more curves
Green, is the track I am planning to add, it would be for slow cars
Orange, this is the place where all cars are placed
Pink, is the place where pits would be, however I am not quite sure how to make this part, I dont really know how a pit is
So yea I need a little help at pits
