Happens on a daily basis Ruby. I had a moron flash his high beams and lean on the horn at me because I was doing 60 in a 60 zone and changed lanes in front of him while easily 2-3 car lengths in front of him. And he was in the right lane doing a max of 50.
Nearly every morning on the Port River Expressway there's someone doing 70-80 in the 90 zone and yes usually they're also in the right lane. Pretty sure a car got pulled over this afternoon doing about 60 in the 90 zone. Then there's those that change lanes without indicating, slow down at intersections (maybe waiting for a red light...?), those that speed up on yellow signals and run red lights, those that can't drive straight in their own lane and wander into both lanes, use the 3rd lane (the ones that merge into 2) at some intersections and then go slow enough to have to stop and allow traffic to their right pass..... and all because here in Adelaide there's too many fktards allowed on our roads. I could go on....
