Yesterday, I attended a speed awareness course. I was caught at 35 in a 30 zone (in my defence I was decelerating and it was a genuine mistake). I was given the option of a £95 course instead of £60 and 3 points.
During the course, the instructor, a knowledgeable but catastrophically monotone former traffic cop asserted that the re offending rate for the speed course is better than that of the points and a fine. My inner stat geek started screaming: SELF-SELECTING SAMPLE. People offered the course have
- not offended in the three years previously
- been caught a small amount over the speed-limit
- be prepared to spend extra to avoid points therefore probably wealthier
- be willing to spend half a day taking the course.
