Law enforcement faces the challenge of stopping fleeing
vehicles. Non-violent methods include roadblocks and spike strips laid across the pavement. However, neither is entirely successful
because drivers sometimes avoid the barriers.
The manmade device from Home Security, named
with typical government verbiage, is called the “Safe Quick Undercarriage Immobilization Device,” or SQUID for
short. It is the size of a manhole cover, several inches thick, and filled with coils of strong elastic band. The SQUID is
placed in the path of a moving car or truck. It can be camouflaged and unnoticeable to drivers. As the vehicle passes over,
the elastic bands spring upward and tangle with the axles and drive shaft. As a result, the vehicle comes to a quick stop,
similar to locking the brakes. Preliminary tests successfully stop a small truck moving at 35 miles per hour. A YouTube video
