Around 10 years ago, I was driving back from a friend’s house down in Dana Point. It was around 2 am, and as I drove back, I remember feeling as tired as I have ever felt. It was one of those times where, even though I hadn’t been drinking or anything, I probably should not have been driving. But I was stupid and overconfident in my abilities, and I don’t think my brain will ever lose the acute feeling of terror I experienced upon being jolted awake by the bumps on the shoulder of the road under my tires.
