1ADH 690 - oldish red Pulsar.
cruising down Marmion in me ute, on the 80 speed limit, approaching an intersection, (I thnk it was Warwick). Green light, I go to drive straight thru. This red pulsar to my left, turning left, waiting at the give way sign, decides to pull out into my lane, just as I'm crossing the line... there's a car to my right so I can't swerve, just have to hit the brakes *extremely hard* on the verge of locking up. A solid blast of the horn .... pass him a bit down the road after I get into the other lane, and notice the dopey twit has earphones in, so he's probably oblivious to the whole thing. Youngish looking guy, but no P plates.
A big white Falcon ute coming at you at 80km/h is pretty bloody hard to miss I woulda thought... <_<
another use of the horn about 10 mins later when a prick in a 4WD didn't give way to me on a roundabout.... narrowly missed him, unfortunately didn't get the plate
that's 2 out of the 3 times I've used the horn in over a year of driving it.
