>>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.

they have some cats eyes round here that store daylight and light up at night. Looks neat when you see them behind you and they are lit up.
