when I get buzzed I shout "Hey". I can usually get it off while the rear of the car is still next to me and so if I yell loudly I know they can hear me. gone are the days of getting buzzed with impunity. I recently rolled up to a guy who buzzed me who got caught in line at an intersection, actually he rolled along side me reeeeeaaaal close then accelerated away. he could see I was approaching so get this, he turned his head like he was looking at something to avoid contact with me, but I stopped at his passenger window and waited for him to notice me, but haha he purposely kept looking out his window. but traffic wasn't going anywhere so I tapped on his window, he acted surprised and rolled down his window, he seemed nice enough, middle aged chinese guy driving through concord, he had golf gloves on his passenger seat, whatever, so I said: "you got pretty close to me back there" and he said "oh, oh, I didn't know" ... so lame ... so I said "let's keep your eyes on the road ok?" he just stared at me. as I rolled past the line some guy in a pu truck a few cars ahead yelled out his window "F**K YOU YUPPIE" I just kept going. lol, yuppie, what decade are you from? can't you notice I'm not a young upcoming anything anymore? good grief
