I would add to this that those who do see you do so with a bullseye and cross hairs on you.
I’ve had situations where people gun their cars to try to cut me off as I make a lane change and do so with the intent of scaring the crap out of me. I’ve been riding so long the only thing it does is pisses me off. I usually give them an ear full at the next light if they have the guts to not pull off first to avoid having to wait next to me.
That never happened to me on my bike. It DID happen to me on my bicycle a lot though. One was a harley rider. As I am riding he starts riding next to me and gives me a 30 second earful on why us bike riders are a menace, blah, blah, blah, and I just listen.
When he is all done I looked over with an excited look in my eyes and said, excitedly, “Hey, I have a motorcycle too!”. He just gunned it and took off.
Gawd he was pissed.
