When I was younger I would get road hypnosis, particularly at night. Don't even have to be tired, just start "zoning out" completely despite doing things to combat that (roll down windows for fresh air in my face and blast music).

I feel like this lightened up a bit in my late 20s. In any case, I love that I now live in a city where I don't have to drive and do not own a car.

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.

I wouldn't even try to use AutoPilot for this reason. I'd fall deep asleep if I wasn't actually steering the car.

I get active cruise control. I don't get lane assist. Doesn't everyone else's mind just perform steering pretty much without thought anyway.

One of the biggest fear that stops me from buying a four wheeler. I have fucking slept on my two wheeler :(

(Yes, it’s a concern and I’ll be a danger to others as well. I feel so comfortable and sleepy on moving vehicles)
