Mirrors stay cleaner? Where are they putting these things? When we put them on the van, they only altered flow from where we put them on back. I could believe that the wake would be easier to see through (presumably faster moving, pulling the wake inward thus easier to see around the rear wake), I am sure it would have helped keep my friend's rear window stay cleaner, but I don't understand how it would possibly help keep mirrors cleaner (unless maybe it's a mirror that helps to keep an eye on the rear door of a cargo vehicle...). At any rate, my friend was going for low drag, so when our little test showed that his van had higher drag with than without, they didn't get any more investigation.
