i’ve definitely noticed that the nod depends on what bike i’m on/what clothes i’m wearing, if it’s a road bike and i’m in a relatively roadie outfit then most nod, if i’m wearing normal clothes/on fixed gear, a few might by mistake, if i’m on anything else, no way!
i don’t know why there’s the need to recognise other people doing similar things.. but tbh i couldn’t give a shit whether i’m acknowledged or not! we’re not even going in the same direction, i’ll probably never see them again!
