Are these also used as deterrents to terrorism via motor vehicle? Large blocks of concrete to prevent cars and trucks from intentionally going onto the sidewalk to harm people (as we've seen a couple of time in Europe.) Edit: after looking at the pictures closely it does not look like they have been placed in such a manner that they would be so I guess the answer is no.
