““his or her brain is conditioned to not see a motorcycle so his or her subconscious may ignore it, focusing on what it does expect to see (cars, trucks). This phenomenon is called inattentional blindness. In other words, if someone is not thinking about (attending to) something, he or she can see it but not comprehend that it’s there. A bike may appear as just a foggy blur. It’s not only that the driver’s eyes don’t see the bike but also that the driver’s brain is programmed to ignore motorcycles as nothing of importance.””
