Is it time to start calling out bad cyclists?

I did something very stupid the other day.

Riding along north bank between chelsea and pimlico along the main road (40mh I think), I noticed a cycle lane on the very wide pavement, so I swerved onto it to relax away from the speeding cars, only to find it was only 100m ish long!? As I was annoyed at such a stupid setup I didn't give my re-entry to the main road much consideration and came about 2cm from a speeding mazda.

Really close to something seriously bad.

Only this morning I took out some poor bastard's left-hand wing mirror in standing traffic because I thought "fuck it, i can get through that 3 inch gap he's left from the curb NO PROBLEM"

Could still hear him beeping furiously at me from about 3 miles away .

Facepalm.
