Someone (names have been removed to protect the innocent) has been warning cyclists that City of London cops have started giving on the spot fines to cyclists who go through red lights:

A colleague told me about it during an after-work drink, and about half an hour later ... on my way home along the deserted City streets I saw a cyclist (in Queen Street) getting his card back from a police motorcyclist. He hopped back on his bike and when he stopped at the next set of lights I asked him about it. 'Done for going through a red light. 30 quid fine.'

Another cyclist responded:

Ah well, if the streets were deserted it sounds like the traffic cop was just bored. One example doesn't make a trend. And one fine for one violation every x number of years for doing something you do several times a day every day isn't going to stop anybody who does it either.

That's the spirit, eh?
