And perhaps there's no marketing value in having a car with excellent rust resistance as we live in a throw away society so who cares if it'll last more than a handful of years.
Madness if you ask me.
. Just make it look pretty and pack it with gizmos and away you go.
I'd have a manufacturer liable absolute minimum life expectancy of 10 years on all none service items (electronics etc.) and much, much longer than that on bodyshell etc.
That way we wouldn't be throwing away so many massively resource hungry items (aka cars) so quickly.
But I'm dreaming aren't I.......
