We don't have them in Canada because they prevent us from using snow plows on the road.

In my part of Canada we do. Or maybe I should say did... until the snow plows got them. I live in Prince Edward Island and they were put in in some especially tricky areas just last summer and already they are mostly gone. They were the type where they cut a little dip in the road and install them so that they are even with the height of the pavement and that didn't even save them. The glow in the dark paint on the other hand would be a huge improvement and not susceptible to damage. Not to mention no installation required.

  Interesting. The Gorge in OR has the sunken markers and I've yet to see one show up missing during the snow season. Wonder if there is specific method to install and also for applying the snow plow to cause the reflectors to stay in place.

    I don't know about the whole of PEI - I only lived in the Summerside area for a little over a year, or two winters' worth, before the Canadian Forces Base closure was announced - but in my experience snow was not anything like occasional (or vertical, for that matter; precipitation is a horizontal phenomenon) and ground stability is an old civil engineer's wife's tale. The island is essentially a waterlogged sandbar with a plastic surface that almost seems alive during the frost season. Shallow roadbeds ripple with the seasons; deep concrete slabs tend to shift significantly. (The slab-bed highway around Charlottetown looked like a post-earthquake scene in the spring of '89, and a brisk business was being done in tires, wheels and steering and suspension parts.) There isn't a lot that works well "everywhere" that's directly transferable to PEI. The only way to make sure that inset features stay inset is to sink them deep enough to be more or less useless.

In AZ, CA and OR (only states I know for sure) in the snowy areas, reflective markers are placed in a divot removed from the area between the painted lane markings. It works and is not very noticeable when changing lanes. As soon as you get to the areas where snow is minimal, the divots stop. I've not noticed other states (WY, CO, NE, KS) doing this.

They're present on some BC roads, where it doesn't snow as much.
