My first speeding fine was for doing 48mph in a 30 one weekday afternoon. Only just past my test and trying to show off to the girl-friend (note trying in an ultra slow Austin A40 ). The fine was a fixed penalty SP40 around £40.

The only other time I got caught was doing 36mph in a 30 at 1:00am in the morning in my late teens. This time however I got an arrogant copper who wouldn't give me the fixed penalty and tried to do me for careless driving, insisting on a court summons. When at court the case got dismissed and I was just issued a SP30 but court costs etc. came to just under £300
