i don't own an Xbox and haven't played a forza motorsport game - so, forgive me if i'm wrong - but i've been watching this
guy's youtube channel recently and it completely baffles me that forza doesn't seem to penalise ramming and crashing. shitty racers usually get away with slamming others off of the track whilst clean and respectable racers suffer. i've recently been getting into driveclub and - despite it being more arcadey than forza - even that penalises heavy collisions to disincentivise playing the game like burnout. it's just really odd to me that a simulator doesn't do anything about this, especially in online lobbies.
edit: oh haha, someone's posted one of super gt's vids that highlight this issue in this thread
