UK; they’re all over the place here. You see them in lanes (such as the video) that are restricted to busses. Like my cats and their flap, the busses have a sensor that makes the bollards rise and lower so that they can get through, but prevents other traffic consequently.
Other times, they’re in place to keep out ordinary traffic, but to let in delivery vans or emergency equipment (such as at my university). *
Sometimes you see them along the entrances and exits of shopping centre carparks, to block them at night.
If you find cars getting stuck on them hilarious, and don’t mind annoying-as-fuck music, there are loads of such videos on youtube.
*Parking at my uni is tight, and within minutes of these bollards being lowered, some twat of an undergrad tries to drive across into the area that they were blocking – which would mean more or less parking on the campus common between the buildings (ie a very obviously NOT a parking area).
