"The narrow 30-foot median contains only a low earthen berm"
Don't you have to be driving like a bit of an asshat to feel like 30 feet of earthen berm is not enough between your lane and the oncoming lane? That's a pretty big barrier and the road in question is straight and level.
Don't know what the speed limit is there, but when an asshat is out of control at over 40mph, I wouldn't consider 30 feet of grass a "pretty big barrier" between myself and them.
