Not perceptions - based on facts and personal experience over many years.
Fact - my car has never been damaged or broken into in a secured cruise car park.
It has in public car parks.
Fact - Most Car Insurance will not cover loss/damage if car left unattended overnight / for several days in a public car park - reason ? actuarial statistics on theft damage from public car parks.
And peace of mind (perceived or real threat ) is worth a premium - to me.
