Just happened to me.
I went out for a ride this morning, first "real" one of the year. Coffee, leathers, nice weather, new inspection sticker - just an all around relaxing day and great afternoon for a rip.
I'm heading home on the highway, in the middle lane, and I notice car in the right lane coming up beside me. I look over, and it's a teenage girl, going maybe 5-10mph faster than I am. Right as she comes up along side me, I look over and notice that she is completely face-down looking at her cell phone, which she's resting on the steering wheel while texting.
I expected it, and she starts to drift into my lane. At this point I am RIGHT next to her, and there's a car about 4-5 car lengths in front of me so I can't just speed up. So I do the "polite" thing - I pull in the clutch and wrap the throttle to around 14k RPM on the R1.
It startled her so badly, that she jerked up from texting-posture, and in the process flung her phone right out the fucking window. If I had better reflexes, I probably could have caught the thing - that's how close it came to hitting me.
I have never had a more rewarding thing happen to me, ever. It's bad enough that she was completely not paying attention to the road, but to have the window down and not "notice" that there's a 1000cc sportbike next to you at 80mph?
