Whenever these discussions come up, I often think of a time I was driving on a two-lane road in rural Ohio in the 90s and at one point the center stripe curved into the lane (presumably because the driver of the striping truck pulled over without turning off the striper) and I started to curve off the road thanks to subconscious interpretation of the cue. I caught myself before I drove into a corn field, but human vision systems are also susceptible to these sorts of problems.
