Bar end mirror........the only way to go in my mind. I never change lanes with out giving my head a turn and confirming the all clear but I think that is out of habit because I have never relied on the mirror and had a vehicle there when I turned to look. If there is a car in the mirror why even bother looking. A mirror enables me to keep my eyes on the road for more of the time. It also lets me see what is comming up behind me like a bus or some joker trying to get the drop on me.
