I hate to continue your tangent but I do feel something that is relevant to the OP article are new vehicles that have blinking break lights.
Most people don't notice these new break lights (I think its on Chevy cars) but when the driver breaks there is a very fast and subtle blinking of the red tail lights (opposed to just the red tail lights being on for older cars).
I only noticed this blinking while under... but now I see it often but my wife does not. ie its similar to the pong bar "C" letter in the article.
