Auto-targeting side mirrors

I see a few suggestions for blind spot sensors, but nothing for something that would actively minimize blind spots. What about mirrors with sensors that could detect a vehicle in the adjacent lane, and automatically adjust the mirror angle on the horizontal plane to keep the vehicle in view as long as possible?

I agree something needs to be done about blind spots. I own a 2010 GT and the rearview mirrors are so small. I recently was told I ran a woman off the road because I did not see her, and unfortunately now have to agree to pay over $3000.00 worth of damage done to her car because I did not see her! This is a real liability and in my reality I do not want to drive the car anymore........have nighmares about the whold issue
