Always so sad to hear...I'm sold on the use of glasses mirrors. Cannot imagine going on the road without one, I hear a car and look just to see if its ok. Several years ago I was almost rear ended by a car one night while sitting on a motorcycle at a red light. Screaching tires from behind and about 1/2 an inch from impact.That was the longest four seconds of my life. Now with bicycles I always use one.
