What drivers are, and are not, used to seeing is often tossed out as a reason cyclists are missed. I don’t buy it. Drivers are used to seeing other cars yet they smash into them all the time.
Drivers are not used to seeing UFO’s, yet if one landed in front of them you can bet your cycle shorts they’d likely see it and do their best to avoid it. (shock and awe factor)
Being well out of the ordinary garners attention. Be the UFO and don't be shy.
