I did one mmaybe 5 to 10 years ago.
The course givers were quute up front, get awkward argumentative or disruptive, you'll be off the course immediately and given the points.
Not surprisingly, everyone was attentive, actually joined in the discussions in a constructive way and I thought it was very good.
Most attendees seemed knowledgeable on speed limits and why, signage , road markings etc
I seem to remember maybe one guy mentioning cyclists , not so much a rant, but it would be a pointless exercise, we're not here for that. Might as well moan about traffic, pedestrians potholes, anything you can think of...pointless.
I thought I was going to get chucked off before it even began. As they ran through the dos and donts, they were going to check everyone's photo id / license, without ID, you cannot proceed
. Errrr, I havnt got photo ID and only an old paper licence I'd stubbornly held onto. It was no problem as it happened...
