Yikes! Glad you made it through that close call!
It might be a matter of adjustment. I had a hard time with my mirror in the beginning, but eventually I got it to a point where I could scan the left/behind with a quick glance up and left -- and even if I angled the mirror higher I could see behind me to the right as well. And I think when you need to make a move to the left, a long time earlier be scanning behind, make a lot of checks so if anybody's nearby you will have seen them in multiple glances before.
And of course always one last check for real before risking a move.
