There could be a number of possible causes for this collision--distracted driving, which includes, but not limited to, cellphone use. But the idea that the driver 'saw' the cyclist but didn't actually 'see' him, that is, it didn't register in his brain, is something that I've encountered quite a number of times, most frequently when drivers are making right turns in front of me. They are looking right at me as I am coming through the intersection, and numerous times I've had to slow down or stop to avoid being right-hooked. Also numerous times I've caught up to the driver at the next stop light and confronted them. The common response is, Oh, I didn't even see you. My response is usually, You were looking right at me and you didn't see me with my two brightly flashing/strobing lights and my super fluorescent jacket?! Get the **** off the road and get your eyes checked!!!
I'd be interested in hearing more details the Bradley collision as well.
