if something isn't moving, it's very easy to miss. people naturally notice contrast, whether it's color or movement. bikes are especially difficult to see from a side profile (i.e. pulling out of a driveway perpendicular to the main path of travel)If you stare at your cell phone like the dot yea, it might make a motorcycle disappear.But if your scanning for hazards it shouldn't affect you bad enough to miss a dark silhouette with a headlight, I understand misjudging speed, but not this.
I think thats just a high tech exscuse.If the sun is blinding you, you dont just stare at it.Same thing with oncoming headlights.If you have to squint your eyes from the sun, and go through a intersection blind, or simply pull into traffic from a intersection with blindspots.You shouldn't just do it.You slowly pull forward hoping your vision will improve, or unseen traffic can alert, or avoid you.
Regardless of the circumstances that make a blindspot.Its the drivers responsibility to identify them, and proceed cautiouslly.It really doesnt matter if its a eye phenomenon, the sun, a accident merging lanes on the freeway, or one in town at a intersection.A motorcycle only uses 1/3 of the lane.If the motorcycle wasnt seen, or given enough time to change course or brake.It was the brain of the drivers fault, not the eyes.
