The "salute" should be amongst friends in a familiar setting: an ADV event for example. In general public, the "salute" is an uncontrolled hostility. Perhaps not from your pov, but from nearly any other perspective that might see it, children, etc.
I was riding my Uly through Sultan WA today and I saw parked in a lot a BMW with an ADV sticker on the back and a guy standing next to it with his helmet off. I beeped my tiny Uly horn and he looked up and waved. I gave him the bird, and he busted out laughing as I went by. If I offended some children I don't really give a shit.
