Check your data before you start swinging accusations around big fella.
Have a look at this:

"Statistics both in Australia and Sweden are
highlighting their excellent crashworthiness
characteristics particularly on rural roads and
freeways (Larsson et al, 2003) with as much as 90%
reduction in fatalities wherever they are installed.
However, despite this good record, there are still
some contentious issues regarding the use of such
systems. The first concerns motorcycle safety which
is discussed in another ESV paper (Berg et al, 2005).
The second issue concerns vehicles under riding the
wire ropes (Figure 5) for various reasons including
inadequate rope tension because of poor
maintenance and/or installation. The third issue
concerns whether such barriers can adequately
redirect rigid and articulated trucks."
I did not mention concrete barriers or steel barriers. I was simply referring to the data which suggests that wire rope barriers dont always work. Particularly for heavy vehicles and those with a high COG.
If they are so safe for 4wd then how bout this:
Burrumbeet crash: anger over wire barriers - Local News - News - General - The Courier
"Two people died on Friday night when the four-wheel drive they were in careered through a wire-rope barrier and into trees"
They have been shown to be effective as median barriers - but not on corners. Why are they still being installed as corner barriers I ask you??
Also a more motorcycle focused report:

Seriously though all Im suggesting is that no single means of vehicle safety barrier is going to be failsafe. I still believe that wire rope barriers are not the answer. Primarliy because I ride a bike I suppose and want to keep all my bits attached.
