I must be in the minority then. No issue on mine although I do tend to look over my shoulder by habit being a biker.

I'll also say I have those mirrors on my work hack, the ones with the end that bends (Skoda Superb) and I bloody hate them. I know it's a specific scenario but my commute is 107 miles each way, and 103 of those are motorway and what I find is that they make it look like cars in lane 3 are coming straight at me, even if I'm in lane 1/ Net result I still look over my shoulder.
