Back around 1970, I drove down to Florida with a couple of co-workers. On the way back to NJ, we decided to drive straight through, instead of stopping for a night or two. Now, bear in mind that I-95 was far from being complete in those days, but even with the inevitable detours to older highways, somehow we managed to drive from Daytona Beach to NJ in ~19 hours.
On the final leg of the trip, as I and another guy slept, the third guy was driving the Maverick, and suddenly the two of us who were sleeping were jarred awake by the lurching of the car. I looked at the driver and asked him if he and the car were okay, and his answer was, "Yeah, everything is fine. I woke up when we hit the gravel on the shoulder".
Even though I was still very tired, after that near death experience I managed to stay awake for the remainder of the trip.
