Is it time to start calling out bad cyclists?

He just said the guy spat over his shoulder not necessarily at him.

On some of the rare occasions I've been prompted to shout while cycling I've found my general mouth-throat canal too swamped up with saliva from being so unfit, that the resultant effect is garbled speech and spittle spray. Maybe he had the same problem.

This falls on deaf ears I'm afraid. Whatever the intention it's not really ok to me. I've never needed to spit for my body to function and I'm riding the same bit of road, at the same speed and effort.

If had a medical reason that required spitting in the road – then I guess I'd do it whilst nobody was behind me.
