Ditto.
I was coming home from paintball one day in the 32, had the mrs in the car.
Cruising along in the right hand lane and all of a sudden a new Range Rover sport that was stuck behind a trailer started pulling into my lane, I was in his way so dabbed the brakes and gave him a toot to let him know there was actually a car where he wanted to go.
Cnt flew off the handle, he passed the trailer then pulled back in the left lane and as I got next to him he winds his window down and starts dishing out the abuse and middle fingers. I was like whatever mate and flipped the cnt off back. Next thing I know he swerves at my car (on purpose), not once but twice - second time only inches off my wing mirror. I didn't balk because at 100kmh on the highway I'm not going to swerve and end up on the shoulder. Dropped it back to 3rd and GTFO of there, pulled into the left lane and slowed down then started reading out the dudes number plate to the mrs so I could ring up and make a report when I got home, he backed right off when he realised we were writing his plates down.
Pretty sure nothing eventuated but as far as I'm concerned, trying to run someone off the highway at 100kmh is attempted murder. I know the car, the face and the plates - god only knows what will happen if I see him again.
If you have your mrs in the car, her safety should be foremost. Any other time, they'll meet Mr. 4D-cell.
