[24] The injection system used by NASCAR is a different system from that used in IndyCar Racing and other motorsports series; the EFI system that NASCAR put into use was compatible with the old restrictor plates, allowing NASCAR to continue to use them to keep the speeds lower at the superspeedways and save costs for race teams. The NASCAR season kicks off annually with a 500 mile restrictor plate race at Daytona. The drawback to the use of the restrictor plates has been the increased size of packs of cars caused by the decreased power coupled with the drag the vehicles naturally produce.

If the speed is high enough air flowing over the car's overall airfoil shape will create sufficient lift to force the car to become airborne. The reduction in throttle response, however, has never been shown to have impeded the ability to pass; the criticism was shot down in the first "modern" plate race, the 1988 Daytona 500, as the lead changed 25 times officially and saw several bursts where the lead changed several times a lap and also several bursts of sustained side-by-side racing, notably in the final 50 laps between Bobby Allison, Darrell Waltrip, Neil Bonnett, and Buddy Baker.
