Racing seats and harnesses keep the driver secure. Fire suppression systems reduce fire risk. Helmets and HANS devices protect the head and neck. These combined systems help drivers survive crashes that would be fatal in normal cars. #facts #knowledge #viral #fyp #didyouknow reels technology innovation experiment"
