>Talking of cats, we seem to be the only country in the world to have "cats' eyes" demarking lanes on our roads. A British invention, they're like pairs of wee reflective discs, set in a rubber "bunker", that can squash and rebound as cars drive over them. They reflect your car lights and resemble the landing lights of a runway. Lane dividers - white, kerb markers 0 - red (as in NO), intersection boundaries - green (as in can cross), mediajn/outside lane boundary - amber. I miss them when I'm abroad (not meaning "out of doors") as they so perfectly illuminate your way for you.

Actually any catadiopter (another official name from the OZBS - Basic Law on Traffic Security - that you have to learn when you get a driver's license) is colloquially called "cat's eye", regardless of its location. It can be on a car, bicycle, or sometimes even on the road, though I haven't seen too many of the last kind when I was home. Our roads have very little in terms of signalization, but that's compensated by the number of potholes.
