The major difference being, that ours is mandatory. You can make it as hard as you like, but if people can opt out, what's the point? I honestly don't know how you "sensible" (well, ish lol) riders and instructors do what you do over there, when every day there's just more and more people making the case for bikers worse and worse, because they can, due to lack of control by those in charge.
I do what I do because I know the people I coach come to my school voluntarily. They want to learn. They want to do it right.
I would probably be less interested in coaching in a state where MSF is required. Coaching people who have no interested in being there.. nothing rewarding about that.
