The US State Department in collaboration with Texas A&M Transportation Institute is has recently worked on developing a barrier that is designed to stop trucks that may be carrying explosives.
Watching the perverse destruction in this video is indeed pleasing to watch, however it makes you wonder if something like this should really ever be practical. If the US State Department employs something like this, it will be on the taxpayers dime.
Either way, the design is built on the idea that they will stop your truck, if carrying explosives, at a high rate of speed, all while bringing certain death and annihilation to the explosives in tow.
Whether this idea ever comes to light, we shall see, but for now we can enjoy time from our day to appreciate the destruction.
