Tailgating in a car and drafting on bike are two entirely different things. The first is bullying the driver in front to go faster or get out of the way. Drafting, however, should be taken as a compliment!
Do have to be careful, though. I once braked for a ped on a zebra crossing and the guy drafting behind (no one I knew) went straight into the back of me! But we both laughed about it.
This guy was probably new to the commute and the mean streets of Putney. Still thinks he's behind the wheel of a car and acts accordingly. Plus only a newbie would be wearing lycra shorts in November.
