Not a problem as such, but fairly irritating.
How can I stop the drivers carpet moving / rucking up? Is there an alternative to screwing it to the underlay?

First things first, but not necessarily in that order.
I am surprised that you didn't get a set of the press stud type fittings with the carpet set. It is ok to drill holes anywhere as long as you soak the items with Waxoyl as you fit them.
They are not new carpets Willie , I'm just trying to stop the present ones moving.
I've also got an aversion to drilling holes in cars unless I have to.
