Didn't "see" the bike, saw the bike, but chose to ignore it........you choose.

One of the tricks to surviving when sharing the road with cars is to simply stay away from the group; stay out of blindspots, avoid all SUV's and assume that everyone driving is going to do the most selfish thing possible at any given moment.
If you think the fat ass with the grande latte in the black escalade is going to suddenly jump over to your lane without signalling because they are bored of their current lane.....then 95% of the time, he will......if you anticipate this, you'll be fine.
