Is it time to start calling out bad cyclists?

Gruppy shit box dropped a load of litter on my street the other day. I picked it up and asked him to put it in the bin 30 feet away. He went batshit at me. I can only assume he figured that this was a preferable response to admitting he was being a dirt monger and eating humble pie.

Pick it all up. Place it under the windscreen wiper of their motor. Point made. Job done.
