This link has several other links, including the infamous Steve Johnson photo. In the case of missing his low profile tire, lower beams (as I am suggesting here) would have HELPED the situation, as they would have been below the height of the opening in Johnson's wheel, and guaranteed a longer duration blocking the beams.
Does anyone have a good reason why the beams should NOT be lower?
