I can understand them changing their policy Nick.
When i did BikeSadfe there were 2 participants to each police motorcyclist (who rode in the middle of us 2 participants)
When it was the other participant's turn to lead we came up on a very long sweepy left hander, 60mph limit, with cars doing 50mph, in good bright dry conditions, so the lead participant moved out to overtake. The cop (who was in front of me and I was at the back) moved out to almost the right offside gutter and stayed there....and I followed him. At a certain point he ducked back left to look up the inside of the bike of the lead participant (because he thought he had a gear change problem) and I thought 'shit, do I go back in too ?' Seeing that i had a fabulous view ahead I just stayed out there until the road straightened, in doing so we passed every car very safely.
When we got back the police rider commented "When i pulled in left and you stayed out, that's when I knew you were enjoying the best view"
The other particpant admitted he didn't like to cross the centre line except when overtaking and he never did.......But it was funny that when we got onto a stretch of road with no centre line, he was happy to use both sides of the road then. What a difference a painted line makes !
After the test my instructor asked the examiner why he passed him. He explained he rode so well the rest of the time that he couldn't fail him.
During the BikeSafe classroom session about half of the class said they didn't like the term 'making progress'. We were all middle aged riders who often just like to be on the bike riding not attemptiong to get ahead of any traffic, and it came up in discussion that the imperative to make progress in IAM and ROSPA training was wrong.
Not having had any of that training I can't comment. I think 'making progress' is open to a broad range of interpretations though
Lorries, especially Class 1s, very often straght-line bends. Granted not very acute ones, but we do (Yes I drove HGVs!) cut gentle bends.
I'll often slow down and sometimes even stop before entering a corner to let an oncoming lorry or bus make full use of the road or street.
