have you thought that it might not be you, whose the driver honking with? coz observing the traffic here, i think even those cars in far side of the que honks for the guy's driving the car in the first que, that's how is it here i guess.

mostly it's the first vehicle in line are being honk with even they're in 7th, 8th or nth in line, they just want to inform the first to move fast, but sad to say if you're in front of these guys you'll be receiving the honking not the driver in first.

better ignore them. ^_^
