Why can't GTA4's racing task come out?

The task of picking up the racing car is not to inform you by SMS, but to click on your friend Brice in your mobile phone, and then choose the racing option, and you can race. You should prepare your own car, and you'd better drive a sports car to race, so you have a better chance of winning. Every time you complete 30 MMS car theft tasks, there will be a picture prompt of the next car. As long as you drive to the garage marked "car" on the map, the price of each car is different, and the price of sports car is higher.
