I'd been wondering what on earth those are! I had assumed they were for maintenance workers or some such.
Now I know about them, though, I don't think they're such a bad idea. A bit redundant since everyone has GPS or mobile phones which each provide some degree of placement; but they actually seem a lot clearer than the posts. For one thing, you can read such a sign while driving, instead of having to stop the car and get out. And I can't believe they cost that much as a percentage of the general cost of motorway building and upkeep.
