When I lived in Fremantle - Perth a couple of years ago, a fella there was using Amiga 500s to run a Scalextric slot car centre. It was cool. You paid like 5 or 10 bucks and got to race on the biggest Scalextric race track I've ever seen. He used Amiga 500s because the software that ran the track was obviously for Amiga only. That was few years back though. Not sure if he updated since then, but when I spoke to him he said that he couldn't find any equivalent software on PC to run the track. I wonder if WinUAE would work out for him?
