What happens if it's a couple of crashed cars?
cellphone networks and a more sophisticated digital road sign system could help this
i think I've actually pulled debris from the highway before
This only works on the most deserted highways.
420 has his head up his ass. He doesn't realize that in 70 mph traffic, a mangled ladder isn't even seen until the car in front of you barely swerved to miss it, at which point you're past it in half a second. It takes two coordinated individuals, one a mile behind the ladder to run what is called a 'break', and the other on standby at the side of the freeway where the ladder is, to actually get it removed from the freeway.
420, Mr. "I live and drive on a fifty mile two lane highway in the back pastures of Texas", is out to lunch.
