Once you clean it off, adjust your mirrors properly and you won't need those little things.
Here is how.
LOL. I appreciate it, but I drove a big truck for about 10 years, so I am fairly familiar with how to adjust mirrors. I am actually one of those drivers who use my mirrors a lot when driving. Also, I drive a vehicle with pretty decent blind spots, an FJ Cruiser. But, the blind spots are not an issue at all, assuming one knows how to use their mirrors. And the little convex mirrors help a lot when changing lanes.
My wife, unfortunately, has fallen in love with the FJ and sometimes I have a tough time getting it away from her, so she spends a lot of time driving it, with the kids, so I like having the extra coverage for safety reasons.
