imagine what a terrorist could do to/with a driveable bottle of compressed flamability ?

Before you say you can do the same with gasoline, let me state that I can ignite/explode a bottle of compressed gas easier and from farther away than what I could do to/with a tank of gasoline.

Harder to ignite (smaller ratio of air/flammability), dissipates upward rather than pools on the ground...
