Yup .... I don't need to see a car at 140 meters (though I can under optimal conditions.) What I need to know is where the car is when it is close ... but no matter if I know its closing speed or not .... I don't care. It is going to hit me or not .... so far, not. And as it gets closer, I use all my senses .... but as I say, each has a preference and none of it is really important.
As long as we are not crushed by the cars coming up from behind us, I don't care if you tow a toddler in a trailer with a radar gun who calls out closing speeds and vehicle descriptions.
By the way, I use a normal-sized 5-cm mirror. I don't even know what a tiny cm is.
