If i can when someone is trying to cut me up i make it as akward as possible for them, and occasionally ive lost it and made sure they dont try silly shit again (flashing you out of the way when your doing the limit and have nowhere to go is my pet hate and have taught a few people not to do it again, its funny when they push the girlfreinds fez when im travelling behind them in my van, as it surprises a few people )
