The only people who ram others are players who cannot win straight up, period. Getting spun out in this game is unavoidable for the most part.
If you're not smart enough to cut corners and take the lead in a clean way, then you're not very good anyways, and you deserve the win no more than the guy you just wrecked.
But, there is no point in arguing. We now have non-contact races, so I'll be playing in those where people win based on how skilled they are as a driver.
I did enjoy the accidental crashes and bumping that came otherwise, but you rarely find other players who will at least attempt to race clean.
