I've always been amazed at the trams in Vegas between the casinos that are I think remotely semi-automated (at least one of them, I've seen an operator in a booth at one terminus, in the Excalibur). Some of them are even elevated! I think the Las Vegas monorail is also automated.
I rode the Las Vegas Monorail, which is automated. It is also elevated. When it gets to the end of the line, they tell everyone to exit the train. Well, I didn't (hey, there's no attendant to make me...)
They then switched from one track to the other. This involved moving down past the station to this stub of track that just ends in midair, with absolutely nothing except the control system to keep you from going too far and crashing down 15 or 20 feet to the ground below. That was... a bit nerve-wracking. It all worked, and they don't regularly fall off and crash, but... I don't think I'd do that again.
But yes, they're automated, and it works, and works reliably.
