[Christ]

I like the idea for highway driving, where I don't usually use my mirrors anyway. In the city, however, it would need a way to be open all the time.

Then again, for the small fraction of frontal area that mirrors usually represent, I'm afraid that just going to a smaller mirror that you can always see out of would be a much simpler improvement.

This is not to say that you shouldn't build a prototype, though. You never know who will buy into something, and at the least, it gets you more fabricating experience, which is always helpful. And you get a new talk piece, for when your non-inventor friends come over.
