For years I didn’t use a mirror. I had tried helmet and eye glass mirrors but they never took for me. Just couldn’t get comfortable using them. I did my ride across the US without a mirror and there were several instances where I had to abruptly move from the shoulder and into traffic and realized a mirror would really be helpful. I now use the Sprintech drop bar mirror and it works for me. It’s not perfect but it helps. On one bike I have them mounted on both sides. Also having it mounted ontogeny right side helps me see vehicles coming up an acceleration ramp on a busy urban road where I’m riding the shoulder.
