Okay, so I'm coming up the 5 fwy. from San Diego, I'm cruisin' 80 or so keeping up with a Black BMW probably around a 2000 model or a little later... Traffic is moving pretty good as we are just getting into Irvine. I get this blip on my radar detector which has been silent for the last hour... I start to slow to 75 and have my eye's in the rear view mirrors, and in both my blind spots... All seems clear. About another 30 seconds and I pass a Highway Overpass where hidden in the columns on the inside of the Diamond lane is a CHP on a bike! My Radar hits 5 bars and I jam on the brakes bringing me down to 70 mph without looking too obvious... I see the cop launching through the gears in my rear view, it's still not clear who he's going to pull... Me, or the BMW??? The BMW makes a casual lane change over to the 2nd lane, and the cop hits the red's and gets in behind him!!! Whew!!! huge sigh of relief!!! That poor bastard in his BMW bought the farm on that one!!!
