Just to be clear everyone, 'Driving other cars' cover - if provided - just gives third party only cover, nothing more. Indeed, there is a lot of confusion, even amongst insurance experts, about the scope of such cover. DOC cover was only intended to be used in emergency 'driving' situations, but policies rarely define thus. I recall a case where someone borrowed a car using DOC, left if unattended somewhere and it was stolen. Can't recall the outcome, but the insurer argued that there was no cover because the car wasn't being driven.
