My Ford car has smaller convex mirrors in the corners of the normal side mirrors and they are a godsend in busy city driving. I really miss them when driving other cars.
I'm surprised to see this is the first mention of convex mirrors. I get some of the stick-on variety for any car I'm driving, as it dramatically increases the viewing angle for my side mirrors. I get them for my friends to put on their mirrors, too. If a $6 item can help avoid any kind of collision, that's an insane ROI.
