Is it time to start calling out bad cyclists?

[QUOTE=erythryphobia;3758531]Many people seem to fall foul of the transparent lycra trap.
Though a cheeky thong can make the drag up Camden High Street a more interesting one.

(at least that's what I hope the people following me think)

No, they think "There goes another fool wearing underwear under their lycra. Has no-one told them they shouldn't wear anything underneath? It's only going to lead to chafing..."[/QUOTE]

Nothing underneath some of the jogging-lycra (as opposed to cycling lycra which is I think thicker) would undoubtebly lead to worse driving and more heart attacks.

What do you do in these situations? I always wonder whether I should let the lady in quesion know or not...
