It's all bullshit.
Institute of Advanced Motorists allow you to become a member and so long as you PAY YOUR SUBCRIPTION every year there is no need to retest. Skills for Life they call it.
RoSPA want you to retest every 3 years or you fall back to being an Associate and your riding skill is not acknowledged any more.
In any event, it's all bullshit.
I've been out on rideouts with both groups and they all exceed the speed limits by some margin.
I've seen RoSPA Gold riders crash. I've seen IAM riders crash.
Ego and Alpha Male syndrome bringing out the very worst in a manipulated hierarchy of benevolent dictatorship, and downright bullying at times.
They've lost the most important aspect to all of this... the STUDENT is the most important person there !!!
They all ride like nutters when let of the leash, including Senior Examiners and POLICE Grade 1. I've seen it way to often over the years.
It isn't fun anymore when 'some' of these groups cant get out of there own arse and power tripping to see it.
Yep, seen it myself. Not only in motorcycling.
For some, self-importance and ego are part of the territory when marking their superiority over others.
They must be very insecure.

all in the name of humbleness.
