I've been experimenting a bit with mirrors on my Insight 1. I taped off all but 2x4.4" on the drivers side to simulate the small size available in racecar mirrors. It was pretty frightening to drive. I think that the reason that small mirrors work well in some applications, like bikes and race cars, is that the mirror can be close to the driver. As the mirror gets a ways away, the reverse image doesn't provide much coverage. I think that the inside "warp" mirror or the "wink" multipane, both used inside race cars, might be a better bet for good visibility. Of course, "good" will always be in the eye of the driver.

Re your idea of the Kamm back mirror, there was a similar picture offered up on this site around a year ago. Forget the manufacturer, but you can probably turn it up with a search. I think the idea has merit, assuming the mirror face isn't too small.

Hucho rates the delta Cd of mirrors at about .01 for the total of both sides. For "extreme" modders, it is probably worth the effort.
