I just ride by myself. No worries, no cares. Just me.

I do make a point to wave at anyone on a bike (that I notice). Most ignore me, even if looking right at me, but who cares? I also wave at every car that passes safely ( I ride in rural areas, so it's not that big a deal).

A couple months ago, I came up behind a big group on a commonly used boulevard. They were obviously "serious" meaning high-end bikes, hairless legs, uniforms etc... A couple of them snickered as I rode around them on the left on my low-end frame (with Ultegra everything, but you can't tell in motion, right?) hairy legs, and plain white jersey. Reinforced my choice to ride alone.

Still rode by them, though
