Making the Long Haul? Get your Coffee On.

DESPITE WHAT THEY might tell you in drivers-ed, drinking coffee is apparently more effective than taking a nap in keeping sleepy drivers alert, according to a new study. An article in The New York Times the other day had this to say:

A driving instructor in the car counted the number of inappropriate line crossings during each driving test. Line crossings were measured because drifting over the center line or off the road causes 65 percent of sleep-related accidents.

The decaf drinkers racked up a total of 159 line crossings while drowsy, compared to just 2 line crossings during the daytime driving test. Nappers did better, crossing lines only 84 times. But surprisingly, the coffee drinkers did the best in the sleepy driving test, crossing lines a total of 27 times. [read full]

    This is surprising, not that coffee helped, but rather that it did so much better than the napping. When I used to drive between So cal and Nor Cal for school, I would stop in Paso Robles and take a nap for just this reason. It would be interesting to see a study that charted the overall impact of sleeping vs. caffene on driving style because I would imagine that caffene might create other eratic behavior (more jerkey, etc).
