It can be quite annoying when you are driving along perfectly safely and within the speed limit and you witness bad or dangerous behaviour by other motorists.
Sometimes they go very slowly and weave all over the place, while other times they sit on your tail and overtake you dangerously. Add to this the people who clearly should not be driving or the boy racer types who have no care or consideration and you have a recipe for chaos on our roads.
Often it is difficult to know what to do in those situations. Most of us suffer from very mild cases of road rage (ie: muttering under our breath) until the moment passes and we carry on our merry way.
However, it seems more and more of us are dobbing in bad behaviour on the roads.
Sometimes it happens so quickly that you don't even think to pick up the phone and report the driver in question.
