I have mine set to just look at that place for a car coming up on me when riding straight. I can move my head a little right to left if needed. But to see other traffic I still look around over my shoulder. At night this type mirror shows the lights coming up really nice giving me time to move over on the shoulder.

This wouldn't work on my 5700 series 105 shifters. Shimano changed where they attach. I had a barend version on my Hybrid and it did work well.
