Coming from South Africa that piece of paper was really confusing and never saw the point in it , the card on it own works well as it should always be to hand anyway .... Although the point system is a waste of time too as you get fined with most stuff so it should be enough....
I don't speed any-more because of high price of fines ,but that should be brought in here as well..Would you speed if the fines started at say £100 no you wouldn't ,with points you always think you have enough time between them to be OK.
Before you say it camera's are a good thing but they really do need more of them around. I travel around 100 miles a day and only see the camera team about once a months ,in SA you were lucky to see just 2 a day
