Is it time to start calling out bad cyclists?

Call out to a guy overtaking me at what I thought was respectable 38kmh along the river going west from Vauxhall Bridge. I never managed to catch up with you on a straight, by the time the gap between us stopped increasing I was doing 48kmh and I wouldn't be able to maintain that speed for long. You made me feel weak, so quite a piece of bad cycling, right?

(Hello to all, one more post, 24 hour wait and I'll be able to start selling what I amassed under my bed in the last 3 years)

Obviously you aren't just on LFGSS to sell stuff though, are you ;-)
