The bristol > bath bike path should be a hotbed of mutual waving but I find it unpredictable at best. The general rule seems to be that if i wave, I get a stony-faced look like i'm some sort of prick. If i don't wave, they'll wave and then be morally offended at how acutely unfriendly I am, refusing to enter in to the spirit of camaraderie such a situation should foster.

I have only ridden that wonderful path a couple of times and it is a right old mix.
If you'd seen me on it a couple of weekends ago you wouldn't have got fuck all out of me as it was the tail end of riding from Brighton. My body was in full shutdown. In fact you may have thought I was having a stroke.
Two tunnels!! Glorious, glorious bit of riding that.
There's too many cycle commuters now on my route to say hello or wave to everyone.
Like you said, in the past you were pretty much guaranteed that any other cyclers were hobbyists where as now it's just a valid form of travel.
I still wave to riders when I'm on longer open road rides. They are still guaranteed hobbyists*.
My only observation with people riding road race bikes wearing all the gear on their commute is they feel the need to gun it everywhere and need to be in front (sweeping generalisation, obviously) .
*EDIT: I don't only wave at hobbyists. I wave at anyone who isn't in a car essentially.
