>>>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.

>In France you get reflectors on poles, at the sides of the road. Give no idea where the centre of the road is. Doesn't matter if you scrape each other's near side, passing in opposite directions, or hit each other head on, so long as you don't stray off the side of the road.

>Driving on the rural highways in Ontario, at night, in the rain can be a nightmare: They have a camber: they're light grey in colour such that the faded central white lines can't be seen under the surface wet; they're full of winter pot-holes; the rain puts an overall sheen over the surface such that you get the visual effect of driving on crumpled cellophane; it's hard to discern where the road ends and the shoulder begins; dazzle from oncoming headlights.

I've been saying that for years. You're absolutely right. When it rains at night, it's impossible to see where the road is. You generally end up following somebody else's tail lights and hoping he/she knows the way. The worst is being the first in line and everyone is following you and you have no idea where the road is.

I can't understand why, whenever they repair roads, they don't just install cat's eyes as a matter of course.
