A good deal of time it does end up that slower and less skilled players end up ramming the quicker players, though it can be good in the odd races to keep things even I suppose, I don't like it though.
The other day I was 500PP racing on Cote d'Azure in my NSX and was finishing from 10 - 25 seconds ahead in 3 laps; boost turned on and it was narrowed to 2 seconds; sorry but I've taken a good deal of time tuning my car, learning the track and practicing, how is it fair that months of practice is negated by some cheat?
Slipstream as strong is stupidly unrealistic too.
