co ordinates?

Would be good if it could be set up nationwide. It wouldn't necessarily have to be just on Ride Safe signs. Maybe just on certain road signs (e.g. speed limit signs, just as an example), or a separate system specially introduced.

This is getting better by the minute! I believe that pretty much every post, lamp stand, telegraph pole, and speed sign has a unique reference number that each department uses to locate them. Problem being that they're not all on the same register!
