I've noticed one thing about people who post threads about this...they always sound like their pis-sed off for some reason. Maybe they had a bad day or waiving at someone almost got them into an accident etc. To me honestly there is no excuse to not waive the other biker, other then not seeing the other riders, thats happened to me and i've seen it happen to the on coming biker etc **** happens, but to not intentioanlly do it thats messed up, i couldn't be in a happier mood or in a good mood to ride and also acknolowdge another rider, to me it really dosen't matter i do it anyways, its easy left arm out split fingers...peACE!, but it begs the question if you have to work so hard to ride a bike, what are you doing riding it anyways?
when im shifting, plulling the clutch in, i just knod my head with my two peACE! figers on the clutch lever. I love it when the other rider has the same enthusiasm, you know why because this way i can weed out riders i want to talk to or socialise with or not. Thats another reason i wave to see the other riders attitude.
to me throwing the peace sign is basically like saying i got your back if you crash, i got your back if i see a cop around you, i got your back as a fellow rider, and peace to you be safe and see you soon. I've even communicated with an on coming biker throwing the left peace, him doing the same, then him throwing the tumbs up for my bike, then me saluting him and throwing a thumbs up to him back going in opposite directions, so i think its not too much to ask to just say whats up. I've also tapped my helmet to on coming bikers 4 of the five guys didn't know what it ment, and got pulled over the fifth one saw me do it again for him, he gave me the salute and i looked in my rear view he slowed down and didn't get booked took another route.
I usually have no problem riders always wave back had a chick smile back and give a girly wave back today at a stop light, but i did have one really arrogant dude give me a cold stare and then look away as i rode past him in the lot knoding my head, thats where i knew the guy was a huge dousche not to be noticed again or talked to in the lot.
moral of the story, let those who hate waiving not waive, it lets happy attitudes stay away from the douschebags.
