And while we're on the subject, another stoooopid road building practice. They pave a section of the local interstate after potholes virtually destroy the road surface. It's all nice and smooth, and then they come along with this machine that digs into the pavement on the lane markers and inserts a reflector. Now, this isn't a reflector like you see in California, it's embedded into the road surface so the plows don't scrape it off. After a couple of weeks, road dirt covers the reflector and it's less than useless.
In a few years after the freeze thaw cycle has buckled up the road at the point where the reflectors were inserted, they repeat the process.
