Looks expensive.

Part of the problem is that the US has a lot of roads. So often, the comparison that is made is not “which guardrail is the best”, but, “which places can we budget to install a guardrail?”

This is why even though the safety of cable barriers is disputed, the overall number of lives saved by them is usually said to be quite positive, because we can afford to install more of them. Hitting a shitty cheap guardrail (or cable) is usually better than hitting a vehicle head-on or hitting a bridge support.

Also, those end caps on that guardrail are not considered a safe design and aren’t really used in the US anymore because they spear vehicles when hit directly on the end.
