There's a major difference: driving one of the legitimate tanker trucks requires a special class of driver's license, which one can't get without extra training and a good driving safety record. (Also, I'm pretty sure you're wrong about every single accident leading to fire. Fender-benders and low-speed collisions do happen.)
