Things cyclists should know … POV driver who's incapable of cycling

Why is it so important to 'identify' cyclists (or any other road user for that matter.)..... but the insistence on identification over 'mere' observation and anticipation seems really strange, is it only once something has been identified ("That's a tree in the road!") that action can be taken? Do people not slow down if they don't know what that thing in front of them is?

I have seen quite a few cyclists (in dark clothing at night) around our part of the world that are appear to be going out of their way to disguise themselves as a bush swaying in the breeze. My anticipation of what a bush is likely to do and what a cyclist is likely to do are quite different, so knowing that the dark shape ahead of me is a cyclist and not a bush is quite helpful.

If you are coming towards me, it is useful to know if you are cyclist or a pedestrian, cos if you are a pedestrian you are unlikely to reach me as quickly as if you are a cyclist.

If you are going in the same direction as me, if you are a pedestrian, unless you slip and fall into the road or dash out into the road, its unlikely that I'm going to have to change course. If its a cyclist, I'm going to need to move over to give you room, and I would like as much time as possible to see if this is going to be possible at the time I'm likely to reach you, or whether I need to be modifying my speed etc etc.

Identifying what something is is essential to anticipating the things actions or lack thereof, and making a decision as to what I am going to do.
