kinetic energy of 20,000 kg at 600 mph = 1/2 (20,000 kg) * 268 m/s ^ 2 = 718,240,000 joules

11,000 gallons of gas in a tanker truck = 33 kwh * 11,000 gallons = 1,306,800,000,000 joules

FWIW, I'd be up for reviewing the systems, but let's not over react.

P.S. Feel free to correct my math if I was off the mark.
