Until the recent spate of car attacks, I had never noticed the multiple concrete posts in front of the UC entrances. But this year I thought about it if someone tried to drive a car through the doors, but then saw how many posts there were in surrounding the entrance.
In a lot of places, those bollards will be disguised as more decorative features, too. A bunch of concrete planters lining a sidewalk in front of a museum or something might be steel reinforced and solidly anchored into the ground. It's primarily done to prevent vehicle bombs, but now that "driving into crowds deliberately" is a thing, it'll be considered for that, too.
