Driving while doing nothing = sleep (Score 1)

When you sit still for a long time and don't really concentrate on anything intricate, your brain starts to shut off. Pretty soon you start nodding off... where you lose consciousness suddenly and without control. It can be in a recliner or a bed or a car, doesn't really matter. I'm in the Army Reserve and drive 140 miles one way to my Reserve Center once a month at four in the morning, and it's a killer. At my day job I go in whenever, anywhere from 9 to noon and it's a five minute drive. So I'm not used to driving that far that early... I have two vehicles, a huge, old, 4x4 gas guzzler and a newer, more economical. In the truck it's easy to stay awake, you've got to constantly adjust your steering because of the worn-out suspension, the exhaust is loud, there's no such thing as cruise control, and you're bouncing all over the place. Keeps the blood flowing. In my car, I have to stop and walk around every 40 miles or so so I can stop falling asleep. I think part of the problem is that most newer cars require so little input to drive. You can drive with one knee and most cars float over bumps. Even if you take your hand off the wheel you'll just go straight. There's no sense of speed when everything is so smooth. Perfect for sleeping.
