Yeah I noticed sprint mode is full of idiot drivers, I was racing yesterday about to take P1 at interlagos on the last lap, the car in front of me decides I'm not getting passed and when I was side by side he starts to push me off the track. I try to correct my steering but because the idiot has left me no room, and is still pushing in to my side I slightly nudge him and get a penalty and finish P4. I noticed in custom GP with 20% + races most drivers seem to be more aware but of course there are still rammers.
Hopefully F1 2011 will have a system implemented so these rammers get a temp ban or something, might be good if you have to gain a lisence to play online that will include you having to show you are a clean driver, but of course we can just stick to racing with other members here for clean, fair racing!
