re: Interstate Cable Barriers

You're still not getting it. The main difference between the two is that the cables "catch" you and absorb the impact much better than concrete because they stretch and break. It is basically a conservation of momentum concept when you break it down

And to your point about them being close to the road, I haven't seen any that didn't at least have a lane's width between the edge of the road and the cable. There is a reason for that also
