Never used a mirror and it seems like those who put them on their bikes haven’t either as they seem surprised when I pass them.

I just kept practicing looking back so I can do it without veering out of my “lane”. Years ago when I rode the track, I could look back for as long as I wanted, just using the lines on the track for straight reference- no potholes on the track though!

Quick look over the shoulder every once and a while works for me.
