Insurance companies rely on lazy / old people who don't shop around and auto renew. They're all robbing, scamming twats.
On a related note some dizzy old woman drove into the back of my car last year, needed a few grand in repairs. Absolutely nothing to do with my "risk" or driving at all. Totally her fault, her insurance paid etc.
Guess what - you still need to declare it on a renewal my premium went up a couple hundred quid.
I can *almost* understand why some people fuck it off and risk driving uninsured.
