I was happy to be given the choice, especially as the speeding offence was only 36mph in a 30mph zone, and was entirely accidental.

And I enjoyed the course, I learned several things about why seemingly daft speed limits are placed where they are, speed limits imposed on vans (which most don't observe) and on trucks, and refreshed on things I'd forgotten.

Only one van driver was there, who said he didn't know vans are limited to 10mph lower than the current speed limit. Now he does.

One woman was there because she thought she was allowed to speed up before a higher limit sign, just like the allowance to slow down after a lower speed limit sign.

Uhhh...!

The rest were apparently just slightly over, caught at 36mph or 47mph.
