Is it time to start calling out bad cyclists?

I was just** asking** down Lombard Street in an easterly direction when I saw a young man, in his 20s, not in a suit, riding a folding bike towards me on the pavement. I moved to block his passage and told him he should be on The road. He said he couldn't because it was a one way street. I pointed out that there was a contra flow cycle lane. I then directed abuse at him and went on my way.

People like that cause huge harm to cyclists as a whole.

ha! was that a correction from wondering/wandering?
