A rather agressive "Wot woz dat, bruv?" from some spotty oik on a BMX, An "FFS", muttered under my breath, amazingly got through his iPod earbuds after he nearly took me out while he was crossing the road.
He did half-heartedly give chase, presumably to try and fight me, but even with two full panniers I could maintain 20mph. I think even he realised quite quickly his little BMX couldn't match that, and even if he could, his gormless mates on foot definitely couldn't.
