Given all that we can’t control, one we can, somewhat, is keeping our distance; and it appears to be one thing that actually helps. (Apologies if that’s been said before - I haven’t read the entire thread, it seems obvious enough that it must’ve been.) By and large I’m not bothered by what others get up to, including cyclists.
God knows I’ve set enough tongues wagging over the years in my neck of the woods, given that I normally ride around helmetless,
hands-free when possible, and wearing earphones (I take special delight going by groups of school kids being herded by horrified minders).
