Is it time to start calling out bad cyclists?

Let me make it clear. I am not the girl that they are overtaking, I am not a girl... I'll be riding at a constant speed, rapidly gaining on a nodder, who will then suddenly speed up so the closure rate slows right down, then as soon as they've passed the girl, they'll slow down again and I'll pass them. At first I thought they were just speeding up as they were overtaking, then I noticed a direct correlation between people speeding up when overtaking and the sex of the person they were overtaking.

You have got long hair though...from the back - in the right light...you could be mistaken for a girl.

Have you found that men overtake you then look back proudly at you and then blush?
