I’ve already expressed my distaste for rising bollard barriers (but the video I linked to then has long gone, sorry), and it’s not difficult to see how dangerous putting strong barriers out of the line of sight of a driver can be. You can say he shouldn’t be there, but the guy in the video attached here was just turning up to service a lift. He didn’t need to have his day ruined, and a company car wrecked, because of a poorly thought out barrier design.
