well, an obvious one, you should be able to review your race afterwards, with the potential of viewing it like in virtual spectator, so you can see where you did wrong and where you did good, it should also explain penalties given during the race...
finally you should be able to export as a movie, and if we had macs we could edit them and put them on our website all for free, but now that we are on pc's we will be happy just to be able to export them;) sorry couldn't help it;)
