bottom line on this study, is if you are not looking for something you wont see it. a biker driving a car will see you , they are bike aware. a group was asked to watch a football match and concentrate on the white strip only. they failed to see a man dressed up in a monkey suit come on the pitch and wave at the camera, when re showen the film the could not understand how they did not see the monkey. perhaps we should all wear monkey suits on our bikes and wave,, lol.
