State Farm also screwed over a guy I know. He dumped their policy after they wouldn’t pay anything on his accident (much less dramatic than yours) where they had some kind of parking related crash with 2 of their cars at home. State Farm told him that he could not be covered for an accident with another car on his policy because he “can’t sue himself” so it sounds like they are only paying out when they have someone to sue about it.
Here in the USA my mortgage on a modestly sized house is half that cost. Owning a home in the EU sounds much more expensive to me.
