A few months ago I wrote a post about the large blind spot in the Tesla. Mark commented to the post:
If you are finding you have a blind spot, this is probably due to the way you adjust your rear view mirrors. http://www.popularmechanics.com/automotive/how_to/4234574.html
Many people adjust their mirrors to close to your car. Follow the advice in the above article and this will make a big difference. It took me about a week to get used to the new angle but I have found it very benificial.
I adjusted my mirrors as the article suggests — leaning them much more away from the car and found that this technique really works. As a car moves away from directly behind me and visible in the rear view mirror, it will appear in one of the side mirrors simultaneously. Makes driving much more comfortable and safe.
For most typical cars, this side view mirror adjustment is simply not necessary.
