Thanks. That explains a lot. It’s the state’s fault, and they know it, unless toxicology (or just maybe, cell phone records) gives them something upon which to hang a prosecution. “New cable barriers coming to Delaware’s Route 1 after deadly crash”.
The cable barriers aren’t particularly good - they tried them here after some cross median head-ons. The ones I know about are being replaced by concrete or steel. The cable is a lot cheaper. It will help, but not solve, the problem.
