Fantastic!
Having beta'd this, I still find it as fun as ever. With the exception of Mario Kart, I usually hate racing games, but Ben, as always, you defy the standards. Great Work =D.
Oh yah, I'm glad that the user difficulty has been changed a bit... with all the new players, it's much easier for the user to get first (playing against the other skilled beta-ers was hard), so yah, it's nice indeed.
