About what you see. Remember that mass varies with the cube of diameter.

Of what? Rock doesn't explode. Steel doesn't explode. It missed the gas tank (though not by much.)

And the people who videotaped the fireball were looking at what, exactly? I'm curious where the person who dropped it from the airplane got a rock with exactly the same composition as a meteorite, too...they're not exactly common...

This thing is the size of a bowling ball, and only a bit more massive. I think you're greatly underestimating the amount of force it takes to puncture a car with a blunt object. (And maybe overestimating the impact force.)
