My drive home from work takes me through some hilly roads. In order to ease their exit from their driveway, some people have mounted on poles the bullseye mirrors that I’m sure we’ve all seen before. This industrious homeowner apparently decided it wasn’t worth the investment, and just took a couple of truck mirrors and called it done.
I can’t imagine that the field of view is all that great, with a flat mirror mounted so far away, but hey it’s better than nothing.
So what it the best non-automotive use for auto parts that you have seen?
