I was watching a show the other night on the giggle box about magic etc. They were explaining how most people only see what their attention is fixed on. They did a few examples using studio members & people out in public. For example in the studio they asked the audience to count the number of times dancers dressed in blue entered & left a light beam on the dance floor. While the dance routine was happening a guy dressed in a penguin suit walked across the back of the stage. After the dance routine the commentator asked the audience who saw the penquin. About 1/2 the audience said they did. What was intriguing was what comment was made later in the show. Why is it that car drivers don't see motorcyclist & smashes occur. "BECAUSE CAR DRIVERS ARE NOT LOOKING FOR MOTOR CYCLES. THEY ARE PRIMARILY LOOKING FOR OTHER CARS"
