I don't drive much at all on busy highways/interstates/city roads but when I do the side mirrors are often unused. The most used is my memory and spatial awareness of the cars around me, the cars I have passed or who have passed me along with the rear-view mirror. If it's tight traffic and there's uncertainty I will turn my head to look. With that said, I can see virtual side mirrors giving me an advantage to the analog version by having a wider range of view, lane change assist with lines like a backup camera, night-mode, etc...
