I had a good one the other day. I came out of a sidestreet and admittedly, i didn't check properly for traffic to my left and pulled out a little too close to a Honda CRV (which, was doing at least 80 in a 60 zone anyways) it wasn't like they had to slam on the brakes, but they really didn't take it to well.
To get back at me, this tool floors it, crosses DOUBLE LINES infront of oncoming traffic coming up to a roundabout, and tries to cut infont me. There's already a car infront of me. I had to slam the brakes on to let them in, otherwise they would have ploughed into a median strip and 'Keep Left' sign at about 80-100km/h.
I'm a firm believer two wrongs don't make a right. I made a stupid decision, but this woman had her kids in the car on the way to McDonalds. If i'd been a prick and not let them in, they could have potentially died, they were cutting it THAT close just to get back at me. IDIOTIC.
So, i made a point of cruising past their car when they parked and copying down the rego. They better hope i don't run into them again or they will cop an earful.
