I just came across a serious bug in this game and it's maddening.
I use my Driving Force Pro on my PC for this game (and Race Driver 2) - when it comes time to do the Gearbox Test, it automatically fails EVERY TIME. With the wheel plugged in and selected as my primary controller, the test gives me 0 seconds to pass (normally, it should be about 48 seconds).
So it's either the wheel or the keyboard - and I am unsuccessful at passing it with a keyboard (tried a few times and eventually skipped passed it).
It's a pretty stupid bug. It's not even a big thing really - not game-breaking or anything, just a nuisance. I ended up turning on the Auto-Upgrade cheat just so I don't have to deal with it.
