Are Drowsy Drivers Akin to Drowsy Test-Takers?

This morning on the Today Show, Meredith Viera showed footage of college students driving while deprived of sleep. Pretty scary stuff. While driving through simulated road hazards the previous day (not sleepy), the Today Show interns navigated the obstacles with ease. That night they were kept awake and then retested the next morning. On the retest, they careened around the course, hitting the bright orange safety cones on every turn, unable to stop when unforeseen objects appeared in their paths. That got me thinking. Do you think there are parallels to the danger of driving while drowsy in the test-taking situation? Can you think of scenarios when a student might take a test, having little or no sleep the night before.
