OutRun arcade game. It was also parodied in the 1960s–1970s Hanna-Barbera series Wacky Races. Circuits Circuit racing is a common alternate term for race track, given the circuit configuration of most race tracks, allowing races to occur any number of laps. A street circuit is a motorsport racing circuit composed of temporarily closed-off public roads of a city, town or village, used in motor races. Facilities such as the paddock, pit boxes, fences and grandstands are usually placed temporarily and removed soon after the race is over but in modern times the pits, race control and main grandstands are sometimes permanently constructed in the area. Since the track surface is originally planned for normal speeds, race drivers often find street circuits bumpy and lacking grip. Run-off areas may be non-existent, which makes driving mistakes more expensive than in purpose-built circuits with wider run-off areas. Racing on a street circuit is also called "legal street racing" with two or more racers involved. Local governments sometimes support races held in street circuits to promote tourism. Legally sanctioned events Most often, street racers bring their racers to a sanctioned track. This may occur when very fast cars are pairing up and racers or gamblers or both do not want the outcome of the race to be determined by the conditions of the racing surface, since public roadways do not usually offer the well prepared surface of the sanctioned track. These racers still consider themselves to be street racers since this type of one-on-one racing is not usually contested in sanctioned racing classes, especially if the race involves the common street race type handicaps (as seen in bracket racing). Such races are usually referred to as "grudge races", which are frequently organised in regularly scheduled events at the drag strip ("Test and Tune" days). In some instances, the race track shuts off the scoreboard that typically would display the racer's performance numbers. Many street-style racers organize entire events at a legally sanctioned tracks: No Time The track's timing equipment is shut off and info on the car's performance is only displayed to track personnel for the purpose of enforcing safety rules. Often, even the racer does not know their elapsed time or terminal velocity until the official time slip is handed to the driver at the end of the race. These races typically have cars that are loosely separated into one or more classes
