yeah, im a bit dissapointed with the online bumper cars action, especially when I get into a race using pro physics... im still getting used to driving with them, its hard enough to stay on the track without being slammed into walls by other players. It seems to be guys using controllers who pull this kinda crap more often it seems. I can usually tell they are using a controller (as opposed to a wheel) cos it looks like their car is trying to break dance
I've found the best way to deal with them is to hang back a lil bit and let them crash themselves out, which they usually do sooner or later. Just try not to get caught up in the wreck. Also, avoid revenge cos it prob wont work out like you hope and will only incite more of this lame behavior
What might actually be worse are the ppl who race well, but then pull dick maneuvers when your about to pass them. Blocking or some rubbing is one thing, but purposely putting you in the wall, or slamming on the breaks when someone is about to slingshot you is very un-sportsman like and kind of depressing.
I had a great 1 on 1 race at suzuka yesterday with some guy, I was within a second or 2 of him the whole race, on the last lap I managed to get past him on that last long turn going into the straight... guy quit as soon as he knew he couldnt catch back... made me loose a lot of respect for him.
Oh well, I could complain all day I suppose, but I've been having a lot of fun despite all this. If you got time to play and you find a good group, try to stick with them, lots of fun to be had.
