Ages and ages ago (almost six years, now!) when I moved here, my moving van very obviously couldn't make it around the cul-de-sac. So, he had to back down the street.
I told him that when he got to the end of the street he wanted to be positioned so that he could turn left.
Well, of course, he either confused which direction or couldn't manuever his vehicle correctly. He ended up having to make a right turn.
Happily, there was an exit for him going that way, but another block or so along, and he'd have been in the same problem as 784's guy.
It constantly amazes me how guys can make those vehicles do things a layman couldn't even imagine!
I suspect 784's guy didn't really appreciate the extra attention, but that's what happens!
