Gasoline is flammable with the right air/fuel mixture and isn't under 4350PSI like the air tank, so if the tank gets cracked or broken the gas leaks out or evaporates out. I'm sure the amount of energy in the gasoline is the same amount of energy in the dynamite but it's not really comparable in this case since dynamite is a solid -> gas explosive and has higher velocity than a gasoline explosion.

Though i googled 300 Bar/4350 PSI and apparently that pressure is quite commonly used in scuba diving air tanks, so it's not like tanks for those pressures have never been used before, and accidents with split/ruptured tanks must have happened and reported. Also the MDI Air Tank apparently has a thick rubber coat over the carbon fibre shell to reinforce it should it ever split, though a practical demo of the tank being hit under the same pressures/forces that it might in a car crash would be good to see.
