One thing that confuses me is why insurance rates are barely affected by IAM and often not at all by ROSPA, yet strongly affected by Pass Plus. That is completely the wrong way round.
Presumably it reflects real-world claims experience. Insurance companies are not stupid, and they are involved in running a business, not making value judgments.
Both qualifications are to a large extent self-selecting - in general, they will be done by people who are more responsible drivers anyway. At 18, there is no other way for the insurers to tell, but by the time people come to do IAM or RoSPA, typically ten or twenty years later, their inherent risk will already be reflected in their claims history.
