I don't usually think about being hit or falling. But the coincidences of these two accidents tell me that sun glare is a factor and I might alter my route until the sun is higher and not a factor. There is a point during season change that the sun is coming up in my eyes during my commute during that short week in the spring and fall I change my direction just so I can see. Of course I have the option of which side of the lake I ride around so I can approach work from the east or the west.
