The club is where you could see lots of rich people. Most of the time, they are just drinking and that is a common thing. All of them do that, but illegal racing is something that most of them won't do. Only a fraction would do that since it is illegal and downright dangerous. The idea here is to drive your car as fast as you can and hope to get at least to the third spot. Aside from the money that you will get, you will unlock another race track. Upgrade your car with the prize money to be ready for the next race. Things will be a lot harder.
