The road markings that I ABSOLUTELY HATE, but which are growing in number/scope of usage here in the US are those thick applique' type of vinyl material lines, arrows, and stop line marks at multilane intersections.
Once those friggen things get wet, they are almost frictionless. If you stop your front wheel drive car on the stop line in the rain or light frost and try to take off again, your tires will spin for several seconds before you start to move. Trying to stop on those goddam thing on a bike can be a real disaster - as if we didn't have enough to worry about at busy, multilane intersections!
The municipalies like them because they are VERY reflective and show up well in the dark, rain, etc. and usually last longer than paint (unless they get scraped off by the snowplows during the winter months, which I always hope for...)
