I switched to the micromirror, and the problem was eliminated. It's important to be able to see what is behind, but it's even MORE important to see what's in front of you!
You don't lose rearward visibility with the micromirror, although you'll notice that you're seeing parts of the field of view with just one eye. You'll want to carefully adjust it so you have stereo vision directly behind you. It took me about a day to get used to it. Combine it with the multivex side mirrors and IMHO the rear view situation is greatly enhanced compared to the stock configuration. AND you can see better in front.
