The other side of the story, I was driving in New Zealand with two motorcycles coming towards me, straight road, lights on noone going fast etc.
All of a sudden the bloke on the 'big' bike decides he's going to overtake the smaller bike (part of a group), he just doesn't see the 1.8L mazda 6 coming towards him?
A massive swerve into the grass on the side of the road, any further I'd have been in a ditch at 40mph and I hoped I wouldn't have silver fairing all over my windscreen...
Point being, there are idiots everywhere!
