It's a bit more complicated than that...
Because they're serious cyclists. And pissed off that the traffic lights mean that they can't get a real jump on the rest of us. A few days ago I overtook a fixie MAMIL away from the lights at Bank. And at St Pauls. And at Holborn Circus. He finally got away from me at Chancery Lane. Boy, was he serious.Why are central London riders on their own bikes so ruddy po-faced* these days?
(The summer seems to have brought out the MAMIL brigade - who are mostly male, but can be of any age. In the poorer weather there were many fewer of them, and much more than a sprinkling of Joe and Jane Bloggses, wearing ordinary clothes and pootling - usually not much slower than the MAMILs.)
