It was meant to be a sarcastic comment. My town's lane markings are so bad they might as well not exist in most places. And when they do repaint them they seem to use the thinnest flat paint they can buy, at night in the rain they just disappear. I know heavy reflective lane marking paint exists because I've seen it elsewhere.

Yes. There also is a version that's set into a groove so that snow plows don't scrape them off.
