Since installing mine I find I use it mostly on two lanes, and, those days that everybody is driving f'n STOOPID (you know what I mean).
So far I've ridden past a few cops, and true, I've got their attention, but I haven't been pulled over for them yet - and I do carry a copy of the Traffic Standards Act on the bike just in case.
With the heat we've been having here in Northern Ontario (35C+ everyday for the last week) people are driving INSANE. 3 bike accidents this week, 1 fatal. 1 of them a good buddy (with a headlight modulator on his VTX, not sure if he has one on his Wing, or even what bike he was on at the time - I suspect the Wing). He's in the hospital doing okay, his wife is still in the ICU. I'm not sure of the details, or even if his modulator was on at the time.
Please be careful out there!
