Exactly right. “Making progress” is one of the phrases that I abhor. I was (many) years ago, an advanced police motorcyclist and I think I can still hustle along quite well.
A mate of mine recently passed his test and I take him out once a week, mainly me following and we have a brew and chat part way round. I have absolutely never once mentioned speed/ urgency/ missed opportunities to overtake to him. I do mention the odd thing on bike control, positioning, obs etc., and his increasing proficiency is naturally translating into “progress”. On a 90 minute ride I might note down 10-20 overtakes that were “on”, that he either didn’t see or chose not to take. As it should be- if you’re not riding within your comfort zone you’re a bellend. There is no inbetween. If I tell him where he “could” have overtaken when he didn’t feel comfortable to do it…. is there a chance he’ll change his (safe) attitude? I’m not willing to risk it. I’ve met some pretty sound, relaxed instructors for both IAM and RoSPA who get it and so I’m absolutely not knocking either of the two. But I’ve met the odd one or two who left me with the impression they were a bit “repeat after me” types.
It’s all about finding an instructor that equips you in a chilled out, constructive way and then one day all those checklists just get the right score or tick. Don’t chase a tick in the box, it’ll all come easily enough anyway with the right support and time.
