I agree that there is a set procedure to "properly" adjust the mirrors. The implication being, if you have a blind spot, you did not properly set them. For this car, the proper position has a very narrow range, you have to be just so and then you dont dare move during your drive or you will throw everything off. Most mirrors have enough margin or extra area to allow you to move around a bit and still see. We also have an E320 which has much more forgiving mirrors..you could adjust the seat, move around a bit and still be able to see fine. I dont think most will dispute that there is a proper procedure to follow in adjusting the mirrors, just that some mirrors have a larger and more useful field of view to them. I agree with the point of view that the government may have that some people are too stupid to be driving, so they put "objects may be closer than they appear" stamped on your mirror, or they refuse to allow people in the US to use convex mirrors instead of a plane mirror. I don't trust the insurance companies or gov's logic when it comes to driving safety. The USPS and advertisers quote bogus "studies" that prove most people want junk mail so they should be allowed fill your mailbox with junk daily. In this country we pretty much allow drivers to text and yak on the phone while driving and do not enforce the laws. So again my view of the plane mirrors being required here is that there is no legitimate reason for it other than perhaps boosting the economy. Who knows maybe the mirrors will be illegal altogether soon.
