Does the IAM (Institute of Advanced Motorists) not seek to improve driver standards (even though people have already got their driving licence) - and the instructors there (some being police instructors) - operate for free hoping to improve driver standards and reduce accident rates and statistics......and in turn - they may learn something themselves.
...I can see both sides of the argument in this (but as a "nearly" PPL holder (and a motorbike IAM holder !) - who is not flush with an abundance of cash) - I would appreciate being able to call on a "safety pilot" as appropriate !
