Considering a rearview mirror
Riding almost all solo nowadays, after retiring last year, and going when the weather suits me.
I ride mostly low-traffic roads with a decent shoulder, with occasional busier streets mixed in.
Electric & hybrid cars, together with electric bicycles, sometimes quietly come upon me.
Wondering if you all recommend clipping a mirror to my sunglasses or get one that attaches to my handlebar.
Even a camera could work, since I mount my iPhone to the stem with the screen always on.
