Yeah, a couple of people have mentioned that. I think because I got the hang of it while testing, I didn't realise that people would take so long to get around the track when picking it up for the first time: based on the fact that the game has more ratings than leaderboard entries (and that the slowest recorded times are in the region of four minutes), it seems a fair number of players don't manage the full three laps at all. Once you can get round the corners reliably, it takes less than two minutes to finish. I'd quite like to expand the game, though, and will definitely throw in a one-lap practice run if I do.
