Athough GT4 is undoubtedly the greatest racing game ever built, there is one slight bug which I've noticed. On The Fuji Speedway 90s ttrack, there's a chicane midway through the track that you can just drive straight across the grass on without losing any time! You need to slow to about 40mph to actually take the chicane properly, but I've driven across the grass at 180mph straight out the other side! This on average saves you about 5secs in each lap, making any races on this track a doddle
