I think it's important to remember that most "Safety Camera Partnerships" operate under the guise of "Police", but in fact are run and operated by civilian staff.
Clarke,
You don't have to go to the place where you got nicked to take the course, they give you a list of centres throughout the country where you can take it.
My advice would be to call your insurance company and ask them how much it would go up if you were nicked for speeding, then work out the cheapest option. Mine didn't go up, so I opted for the three points and £60.
And that I absolutely DO agree with
It's far from illogical if you stop, stand back for 30 seconds and actually think rather than just accept what you're told. People make mistakes when driving at the speed limit or even under it as well as over it by a few mph. There are a whole number of factors in a collision, weather conditions, road conditions, vehicle type, vehicle weight, laden or unladen, tyre make model, tyre condition, tyre pressure, enviroment, external influences, driver distraction, etc etc.
At best it's terrible science to pick out one small factor and lay all the blame at its feet.
