HTCB is expensive, complicates snow removal and mowing, and needs to be maintained after a significant number of nuisance PDO (property damage only) crashes, most of which are unreported.
From a cost-benefit perspective, it is therefore a waste of money and detrimental to maintenance of the roadway if it is installed where it is not needed. There is often talk about how dangerous it is for motorcycles, but studies from multiple jurisdictions have struggled to find a direct correlation and tend to vaguely summarize it as "motorcyclists have a very high chance of fatal injury upon colliding with a barrier regardless of type".
