regarding barriers and the comments. The state here puts up this cable fence between the opposing lanes of the interstate to stop vehicles from crossing the median into oncoming traffic. They seem specifically designed to destroy the vehicle. They aren't a soft barrier by any means, they don't redirect force, or even redirect the vehicle. they disable it. The entire thing is designed to stop the vehicle from crossing over. and it works rather well - spectacularly well in some cases I've seen. It's supposed to be a form of soft barrier - but I've seen cars strike it at very shallow angles and they simply disintegrate. I suppose it's soft in terms of transferring energy to the occupants, but it's sure hard on the cars! there's no glancing off these things and coming away missing paint. if you come into contact. kiss your vehicle goodbye. It's somewhat of a visual deterrent as well. If you installed a barrier to those same specs. there is no logical, and I would think legal way anyone - state or otherwise - could find fault with it.
