Trivia: Which of these features is found inside a NASCAR stock car?
Headlights
Clutch pedal
Passenger seat
Driver side window
The correct answer is Clutch pedal
So why is this answer correct? : NASCAR drivers typically don’t use the clutch pedal to change gears, but the cars still have the pedal just in case. Stock car drivers often prefer a technique called rev-matching, where they match the car’s speed to the engine’s RPM and bypass the clutch. NASCAR cars do not have driver-side windows or passenger seats, and actually have headlight stickers on the cars instead of the real thing.
