I know I'll get lectures about the explosive potential of gasoline, but what happens in a collision between natural gas-powered cars? What measures are taken to prevent a Big Bang? I've seen the aftermath of propane-carrying trucks that exploded and it wasn't pretty.

Check out these tests on natural gas tanks.

There is little explosive potential for gasoline. Mythbusters tried to get a gas tank to explode, but in the end had to actually use explosives to accomplish a movie-style car blowing up.

Gas burns very well though, just doesn’t explode easily.
