What's that combo weigh, 12 metric tons? Maybe more? For sake of argument, 85 mph is roughly 36 meters/sec? So that gives the combination 8600 kilojoules of kinetic energy?
I'm having trouble finding data, but depending on design, cable barriers can absorb 100 to 1000 kilojoules. NTSB appears to only test these barricades at 61mph as a "high speed" test...
So those barricades aren't stopping huge RV, and they're not stopping loaded semitrucks. The test data I found showed a "fully loaded" pickup truck striking the barrier at 61mph had 780 kilojoules of kinetic energy. That RV had over ten times the energy of the pickup.
