Is it time to start calling out bad cyclists?

Cyclist really don't help themselves sometimes, two examples today

HGV reversing out of a building site being helped by builders on a very narrow road. All traffic stopped doesn't stop a few cyclist from riding through the little gap between the HGV and the pavement. A few minutes later it was all clear to go.
HGV stopped at the red lights inside the ASL box waiting to do a right turn on Gracechurch street, female cyclist pulls up right in front of HGV I'm over on the left going straight on I shout that's not the best place to be, she doesn't/can't hear me, so start waving at driver of HGV and pointing in front of him he sees me and gives me the thumbs up.

Both these sorts of selfishness around large vehicles boils my piss. Wake the fuck up, kerbnerds.

Something similar the other day.

Bus is indicating to turn left so I move right to filter however said bus has actually flashed the car coming the other way to turn before him, I notice through the windows of the bus some nob has gone up the inside of the bus so I start waving at her to stop she looks frustrated but then a stream of kerbnerds (top name) all fly through and she realises why and gave me the thumbs up. #csb
