For whatever reason, EA has allowed (and encouraged?) hacking to the point virtually every online event is won by hackers. As an example, in the last top speed event the winners had speed of greater than Mach 1. EA does nothing about this, and even rewards the hackers with in-game currency. So the rest of us assume they are encouraging the practice. In the meantime more and more legitimate racers are leaving.
