Hear hear. People wonder why I do some of the things I do (I've got a fat-ass lightbar, as you can see), one good trick if you're not sure whether or not they see you is to swerve, inside the lane of course, just track it side to side. Gets their attention most of the time. The cops, too, but they don't have a problem once I explain to them what I'm doing. They just say to be careful (no shit, there are cars out there that don't see me!).
I lived in SoCal for over 30 years. I've got some roots down there.
