I wasn't speeding deliberately, had just inadvertantly crept slightly above limit while trying to work out where I needed to turn in an unfamiliar area
There's a bit of minimising going on here. There are thresholds below which you won't get collared. You were obviously over the threshold and therefore not "slightly" above the limit. The thresholds are usually 10% over the limit plus 2mph so:
Speed limit: 20 mph
ACPO charging threshold: 24 mph
Summons: 35 mph
Speed limit: 30 mph
ACPO charging threshold: 35 mph
Summons: 50 mph
Speed limit: 40 mph
ACPO charging threshold: 46 mph
Summons: 66 mph
Speed limit: 50 mph
ACPO charging threshold: 57 mph
Summons: 76 mph
Speed limit: 60 mph
ACPO charging threshold: 68 mph
Summons: 86 mph
Speed limit: 70 mph
ACPO charging threshold: 79 mph
Summons: 96 mp
I got busted doing 37mph in a 30mph zone and its fair enough. I was closer to 40mph on a small road in a residential area - houses either side, cars parked both sides. Really too risky. If I had been doing the limit or under and hit a pedestrian the risk of me seriously injuring would be lower than if I were doing 37mph or 40mph.
I did the course and I have to say there were an awful lot of pompous twats sitting around sneering and saying it was beneath them - we're good drivers and we don't need to be reminded about the rules of the road etc. The arrogance and ignorance was was quite startling. Also, the young guy delivering the course was very good, not judgemental or patronising just conveying the facts. It made me realise how much information I had forgotten since I passed my test in 1990.
