The video discusses the issue of driver fatigue, which contributes to 20% of road accidents. It explores the potential causes of drowsiness while driving, including white noise and car vibrations. Studies suggest that vibrations may activate the parasympathetic nervous system, causing sleepiness, while the sympathetic system tries to compensate. Future car designs might include better shock absorption to reduce this effect.
