I can't hear those stealthy electric cars and those _@)*%&% scare the daylights out of me. I purchased one of those Take a Look mirrors but it's been sitting on my kitchen counter for a couple of months. Shame on me. A mirror would be helpful. A mirror on the right would also be useful to see the cars behind me shooting down the on ramps on the 2 lane one way road with a speed limit of 40mph where cars go at least 50.
