road surface markers.
there are many types, made of various materials.
the markers i'm referring to in this post are the lines which serve to separate lanes on the highway.
sometimes they are painted on. sometimes they are raised bumps installed onto the surface of the road.
they are lines of demarcation, and such a simple idea, providing drivers with a sense of order to what would otherwise be total CHAOS.
if you aren't yet enamored of road surface markers - imagine, for a moment, as i have...
...zipping along in heavy traffic on a multi-lane highway...
and keeping to your own lane...
without them.
pretty scary.
