Online racing is even less fun than practice. Well, that's not really true. At least your expectations are a bit lower. Admittedly, the game is rather new, but I found only two players online. We tooled around the track for a bit but never got into a race.
Most sports games use motion-capture technology to accurately simulate the human body in motion.
I've always enjoyed watching NFL football players tumble head over heels after a good clothesline tackle, and I expect the same from my motorcycle games. The government probably wouldn't want anyone simulating real-world crashes, so Motorsims was somewhat limited in their solution. But these post-crash sequences are worse than anything I've seen. Apply generous helping of Superglue so that no joints move. Put Barbie on her moped and run it into a brick.
