I agree with everything you have said. Absolutely shits me off everytime any of these happen and i see at least 3 of them everyday on my drive to work. Today at a round about i was turning right in a one lane round about and some bitch decided to pull out into the round about when i was literally 3 metres away. How the F&*k could you not see a bright green skyline on a completely empty paved round about!!!!
Then not 2 mins later i was at an intersection waiting to turn right and some tool coming from my left to turn down the street im coming out of, tries to cut the corner then realises im there so he swerves away from me back onto the road he was on except on the wrong side of the road, speeds up, as a car that was behind him is now right beside him, and just misses causing another accident (head on with some innocent person coming down the road and cut off the guy who was behind him making him slam on his brakes also.
So many F*^k wits on our roads that should be shot dead centre in the head!!!!
