Police on bikes

I saw something like this happen at 7pm ish. Did you go down Brook Drive?

I'd just been nearly sideswiped by a grey Merc V15 N0D with a fat fcuk texting and driving on Baylis Rd so was not feeling well disposed. I drew this to the bike plod\s attention and he was all "how do you expect me to catch a car, they do 150miles an hour?" I pointed out that in London traffic a fit cyclist can easily keep up with a car for a while and left them to it.

Saw policyclist pull over a Ferrari in Bayswater about a week ago, the guy had taken the number plates off and the copper just cycled in front of him, effectively corking the car but not quite, pointing at the curb. The thing I found most amazing is that the driver actually pulled over.
