    They have other issues though. They cost more to produce, cost more to install and cost more to maintain. They also accumulate snow, which would otherwise blow through an open W guard rail.

    A third option are wire guards. They’re cheaper on all accounts, don’t get tagged with graffiti and statistically save more lifes. They work best on long straight stretches, but because of the flexibility, they are not ideal for inner city streets where it’s best to avoid any lane breaches at all.
