In a car race, you don't choose the racing course as there are not enough racing course to choose from. Go out there and just do your best. That is what is racing is all about, but this time, things will be a little different as you are given the option of choosing a racing course.
Drive your car as fast as possible till you reach the finish line. Avoid hitting any vehicles on the road or anything at all. That will slow you down and you wouldn't want that since the idea here is go as fast as you can. You'll win some of the price money and you can use it to upgrade your car.
