Is it time to start calling out bad cyclists?

He goes down in a heap. I stop to make sure I haven't killed him, he calls me something rude so is clearly not dead so I ride off.

He deserved it, but I still feel bad.

I'm laughing hard at this because it invoked a scene from Shaun of the Dead where Shaun ran over a zombie, stopped to check if he's not alive, and sped off once it let out a gluttering grow while exclaiming "Oh thank God".
