However, in WhyBeAre's latest video,* he flipped the bollard upside down with the World Editor and then used it to crush the roofs of cars which inspired me to make this.
Simply spawn in the prop and place it where you want it (or drive the car under/into it), use Page Down/Up to control it like the normal bollard or O/P for a fast movement.. No world editor involved!
Made for 0.18.x, could work for versions back to 0.06.x
*At the time of making this.
Bollard but it's upside down V1.5
