Couple of stout fellows....
.... three brothers that i knew of - well, I knew ONE of the brothers, and he was the one to retell a similar tale:

They were heading accross the Nullarbor from Perth (in the west) to Adelaide (toward the east) in Australia for an exhibition kart race at the Aussi F1 GP one year. Two of the lads had superkarts and had put them on the back of their old Datsun ute; one in the tray, the second kart on a frame over the first. The third brother was their mechanic.

The distance form Perth to Adeliade is around 2800km. I've done it on a motorbike in 2 days and that was a hard slog. They were going to do it in ONE, each taking turns at driving. The little Datto could only *just* accommodate these lads across the bench seat and they had to squeeze in, shoulder to shoulder.... which half way into their trip proved to be a saviour - one of the brothers awoke to find BOTH his brothers fast alseep. The driver having his hands on the bottom of the wheel, one arm pinned to the door and the other pinned to the brother in the middle such that the wheel couldn't turn. An auto pilot, if you will.

The one thing to remember here is that across the Nullarbor, the road can go on without bends for many, many miles. (One that I personally rememeber was 96km, marked at each end with a sign warning of kangaroos, emus and camels on the road).

The three brothers never really knew just how long, or how FAR they had travelled with all on board asleep...!
