Vapor lock was a common occurrence in NASCAR, since the cars used gasoline and carburetors prior to the 2012 season. With the introduction of fuel injection to NASCAR, vapor lock has been almost eliminated.
Vapor lock is also less common in other motor sports, such as Formula One and IndyCar racing, due to the use of fuel injection and alcohol fuels (ethanol or methanol), which have a lower vapor pressure than gasoline.
