As for the sun being a factor ... people can argue all they want, but the still photo, taken from within a vehicle, shows Exactly what the driver saw ... and there is no glare. Again, people who need to keep arguing theory because they are not big enough to say, "oops, i got that one wrong," simply need to grow up.
Also, none of the other drivers on the road at the same time, heading in the same direction, hit the cyclists.
Could it be that the driver was distracted by something in the car and drifted over a few feet?
Well ... the driver has already admitted to the first part and the second part is attested to by the broken bikes and bodies .... I don;'t care if someone gets diagrams from a 'science" website .. . Science involves studying the actual information, not the theory, to see if the theory is supported by the facts. Looking up the theory and then denying facts which disprove it is the opposite of science.
it's funny ... if I point out even the slightest thing the cyclist did wrong, i get a chorus of "yeah, blame the victim" howls from the ignorant. In this case, when the cyclists made no error and the driver admitted to being distracted, i point this out and I get a chorus of "Sure, blame the killer."
Ain't life at BF grand.
