How fast do rally cars go?
It depends on which part of the event we're talking about. Let's answer the boring part of it first. On the transits, which are the open, public, normal roads between the racing sections, the cars and motorcycles go just as fast as everyone else on the road. They're bound by the same speed limits as everyone else is, and can be pulled over for speeding just like any other vehicle on the road.
On the roads that are closed to the public, where the racing actually happens, speeds on these twisty gravel roads average between 50 and 70 miles per hour, which occasional bursts over 100 mph on the straights.
