I had a cockhead like this on the weekend, he was driving a red targa top corvette. Pulled up at the lights next to me, lights go green, I take off before him so he thinks I'm trying to race so he floors his slowass corvette past me up to maybe 120kmh (I let him get a fair way ahead), this is on Crimea St in Morley. He then sticks his arm out the top giving me the 'wanker' hand gesture, obviously watching for my reaction in his rearview mirror as he nearly went straight through the bend ahead, had to jerk the wheel left to miss the kerb. What a dick. I caught up to him and gave him a serve, also had to stop myself from following him into the servo when he turned off.
Was a white middle aged guy wearing some stupid hat and glasses. MIDLIFE CRISIS FTL!
