A vehicle doesn't have to be obscured by the pillar for you not to notice it. If you're both moving at a constant speed, anything on a collision course will have the same bearing and appear relatively motionless. If you look left and right, your eyes might saccade right past the target.
- wahern 9y agoI think I found this link from another HN post. In any event, "A Fighter Pilot’s Guide to Surviving on the Roads" discusses this: If you get to a junction and move your head right and left to look for oncoming traffic, you need to understand that you cannot guarantee that you have seen approaching traffic. It is entirely possible for our eyes to ‘jump over’ an oncoming vehicle during one of the saccades. The smaller (and specifically, the narrower) the vehicle, the greater the chance that it could fall within a saccade. You are not being inattentive, you are physically incapable of seeing anything during a saccade. Remember the ‘Think Bike!’ adverts, where a driver pulls out into the path of a motorcycle? I am convinced that it is the phenomena of saccades and fixations that is most likely to lead to this sort of accident.
