Recently, in an unrelatd thread regarding safety, someone open-endedly questioned the result of a motorcyclist if they were to go down where the newly installed cable barrier is being put in. Just the suggestion of that idea made me realize the real threat this new safety device has on a rider.
Today, as a service plumber headed out to south Surrey for a call, I drove by the barrier and noted 4 or 5 of these vertical metal posts having been obviously run over (by a car I suppose) and was not only reminded of this question, but realized that the parrallel state the damaged poles were in probably didn't (I'm supposing here) do too much to stop a full size vehicle from running through.
Now I realize I haven't witnessed an accident with this new system here, but the few accidents previous to this barrier I've seen have usually involved the Semi-Sized Dump Trucks or Trailers. I don't see the barrier being totally effective, and besides the hard impact of a concrete barrier, I ask aloud if it would have been a better choice.
Additionally, I don't think these poles are replacable (or) resetable in a single visit, meaning down time for a safety system that see's daily volumes of various traffic vehicles leaves immediate future accidents unprotected from involving opposite direction motorists.
