While racing is actually a legit sport within the circuit, racing on city streets is illegal. This is because the race within the circuit is safe for bystanders. People can watch racers do their thing without having to fear for their lives. Furthermore, there are no other drivers on the track aside from racers. The problem with racing in streets is that there area other drivers. There are also pedestrians who could be directly harmed by the racers.

In circuit racing, they have all the safety features they need to ensure the safety of both the observer and the driver. They have reinforced concrete walls to protect the observer, cushioning pads on the walls to protect the drivers from high impact crashes, and racing flags so that the drivers can know what is going on in the circuit. These are all necessary for the full enjoyment of the sport. After all, nobody wants to remember a horrendous car crash that affected the observers. They just want to have fun.

Street racing lacks all the safety features that circuit racing has. The racers just drive on streets and highways even if there are other cars and other people in the way. This just makes it more exciting for them since they get more of a rush dealing with the other people on the street. They even have a haphazard way of setting the course: they use street pole banners to mark the way or they just set a course in the GPS systems of their cars. This setup makes it very easy for things to go wrong.
