I'm all for people who don't normally cycle getting on their bikes and giving it a go, hopefully they'll stick at it. Most people looked wobbly but fine, I just didn't appreciate being run into.
This.
I try not to get all high and mighty about less experienced cyclists getting in my way on my roads, but if someone has such poor spacial awareness that they clonk my back wheel when I've been sitting stationary at the lights* for over a minute then they are a totally legitimate target for calling out.
*Happened to me today, and has happened on non-strike days too.
Some people would kill to be so popular.
