Ok, so how do I get past the security... nah, just kidding ;-)
I came across a whole load of old tracks and replays for this game on one of my archive CDs which brought back fond memories of it. I have uploaded them here for anyone who is interested:

Some of these were made by myself and friends, though I can no longer remember which ones. That's probably for the best, as some of the tracks are pretty awful to race on, but they do show off some of the crazy things you could do with this game!
That's what I loved about it. The game would have been a bit mundane if it wasn't for the track designer and replay features. The ability to share your own tracks and replays of your best times/most spectacular crashes with others made it great fun!
