Urban legends can have extraordinarily long lives. Consider some myths about sleep that science and logic have been unable to extinguish: the belief that "you swallow a few spiders every year while you sleep" and that during sleep, your brain rests (in fact, your body rests but your brain stays active). There are sleep myths regarding driving, too: if you're driving while drowsy, you can turn up the radio or roll down the windows to stay awake.
The reality is that the only real way to fix drowsy driving is to get some sleep. Turning up the music volume or the air conditioning simply does not keep drivers awake and safe from motor vehicle crashes.
