Just for fun: Stop that car!

If you’re in law enforcement, how do you stop a speeding car without risking injury to yourself or to the occupants of that or any other car? The folks at Engineering Science Analysis Corporation used funding from Homeland Security's Science & Technology Directorate to develop the Safe, Quick, Undercarriage Immobilization Device (SQUID) program, which includes the following two technologies:

The Pit-Ballistic Undercarriage Lanyard (Pit-BUL™):

In case it wasn’t clear in the video, the net contains spikes that puncture the tire. That car is going nowhere.

The NightHawk™:

Again, the strip contains spikes. Either of these devices can be triggered remotely or activated by motion sensors.
