No intention to debate. You have been clear that it is your opinion that the reminder is unnecessary and governmental overstepping.

I'm Just fact checking. As an example, the safety reminder started in 1971 for 1972 vehicles. The reason is that convex mirrors compress the image. We naturally judge distance by the size of the object so it is easy to resort to our 'programmed' way of calculating distance, especially in an emergency situation. It was deemed important to remind drivers that in the case of side mirrors the natural default calculation of our minds does not apply.

Convex mirrors can usually be adjusted to reduce the blind spot to a safe level if the mirrors are adjusted out to the point that to see the side of the vehicle it is necessary to lean significantly in that direction. I changed to European style mirrors many years ago so I can see the side of the vehicle in the mirrors and have no blind spot in a normal driving position.

In normal circumstances I use the rearview mirror, changing lanes when I can see the entire front end of the car in the passenger side lane.
