The above video is from an alleged drowsy driver in Fayette County, Pennsylvania. As you can see, the woman driving the Jeep is swerving around in her lane, sometimes crossing into the oncoming traffic and narrowly missing a crash, and sometimes swerving onto the shoulder.
Admittedly, the guys who were filming this should have been calling the police to report the dangerous activity. While it's doubtful the cops could have stopped the crash before it happened, it might have gotten them there quicker. As it stands, the person doing the filming with his phone continues to do so after the wreck, instead of calling 911 for help. Stupid? Yes. But it's a great video to illustrate how dangerous it is to keep driving when you're really tired.
I know how tempting it is to keep pressing on until you can get to your nice, soft bed. Studies have shown, though, that driving drowsy is just as dangerous as driving drunk. Quite a few people who would never, ever consider getting behind the wheel after having several drinks will readily drive when they can't keep their eyes open. Go figure.
Stay safe out there, everyone!
