Brmmm brmmm.

What about this idea of raising the speed limit on motorways to 80mph?  I can obviously only speak from personal experience, but surely this would just be doing no more than legitimising the status quo?  As I see it, most traffic in the fast lane is already going at 80 or faster.  And there is a theory, which may or may not be an urban myth, that you are allowed a 10% leeway on any speed limit which if true means that the current limit is really 77mph.  So is this just a PR stunt?
