Who knew that "road blocker technology" exists and is so satisfying to watch?
First off, here's an explanation. Those road spikes commonly seen at car rental parking lots don't magically appear—there's a whole industry out that that produces them. They're called (obviously) road blockers and they're used to "control a?ccess" to places that need beefed-up security, say your local Avis or military bases.
They're not always spikes. Another piece of road blocking technology is seen in this video, which is a block of heavy duty steel that pops up from the ground to stop incoming traffic.
