Welding Truck Highway Hazmat Incident & Explosions

A Youtube video: Welders truck rear ended in a highway accident.

The ensuing explosions, flames and missiles shows what happens when you introduce high pressure vessels full of explosive gasses to impact and heat.

The thing that I find most ridiculous is the moron driving the Volkswagen who appears to be stopped in the oncoming fast lane shoulder to film the explosions. He is at risk of being rear ended as well as being struck by a flaming missile.
