Okay. I made the percentages and numbers up, but not the reality. The reality is this:
I traveled over 3,000 miles, rode through 13 states - twice, and met and passed a whole herd of two-wheelers, both motorcyclists and scooterists, and found that motorcyclists, almost to a person, either initiated or returned a wave from me, a scooterist, while almost half the scooterists I met couldn't be bothered to acknowledge my existence.
Yesterday, my BRW and I traveled over 200 miles and met umpteen motorcyclists. Only three didn't return a wave. We met 7 scooters.... not one returned our wave.
