I don't know about this stuff, Moe.
I just sent an email to famed etiquette expert Leticia Baldbridge about this, and she replied that whenever she dons her Harley Girl outfit and sits behind Moose on his Fatboy, she doesn't feel that there is any obligation to wave to those riding Vespas, Urals(with sidecars), or those South Korean Hyosung motorcycles.
She did however say we should continue to wave to those riding Triumphs assembled in Thailand.
(about the whip thing she said those are for "other purposes", but of course with her being quite the refined lady, she didn't elaborate further on this issue)
