Yeah, nothing ever gets fixed until enough people die because of it. We'll just have to wait until a propane truck drives under a too-low bridge next to a day-care center.

In all cases it's ultimately the driver's responsibility to insure that his vehicle can safely pass along a roadway and it's likely that the wheel holders seen in the video didn't even know what their maximum height was before entering the underpass since none of them slowed down to a crawl to observe and judge the fit before hitting.
And public safety is ultimately the responsibility of the "ruling authorities".
