A few years ago I nodded off on a 50mph thoroughfare. I was jet lagged from a transpacific flight a day earlier; I knew I was falling asleep, but there was nothing I could do to stay awake, and there was no exit I could take. Eventually I drifted into the lane on the left, hit a cargo truck, bounced off and hit another car on the right. Thankfully no one was hurt, but it could have turned out really ugly.
Don’t drive when you’re jet lagged — or fatigued, generally speaking.
Probably extreme sleep deprivation? It can be hard to evaluate the width/safety of a shoulder in that state, or even ascertain whether you're looking at a shoulder or another lane. Scary stuff.
