i have had my fair share of rare occurances with the first 3 gran turismo's. but today i had my first obscurity with GT4. I was doing the special condition events Costa di Amalfi (reverse) "easy"....i started out on the first lap and on the first hair pin i hit the car infront of me causing him to slide out sideways...i got my 5 second penalty when i noticed the car i was racing was not passing me....so i just kept going and i was just about 3/4 of the first lap done when i looked at my mp and saw that the car i was racing was still in the same area from when i hit him...so on my second lap i approached the vehicle where i hit him on the first lap...the car was going from forward to reverse pinned horizontally against the two walls....i just parked the car and watched for about a minute...the odd thing was there was planty of room for this car to turn around....after i was done laughing watching this car act funny from when i hit him, i finished the race.....the only thing i can compare this occurance to is from GT2...one time i was racing with a skyline at midfield raceway, i tried to pit late and the car slid hard into the wall that seperated the pit area and the race track directly on the little sighn that said "pit". the car came to a complete stop and i tried to go into reverse and it was if i was surrounded by glass walls....the car could not go forward backwards or anyplace...i had to quit the race....this is the only thing that i can compare this GT4 rare event....anyone else have this happen?
