@rsjaffe

And yet we drive around with even a larger bomb in our vehicles every day. Gasoline has an energy density of 45.7 MJ/kg

Oh no it doesn't. I guarantee you it doesn't.

A gasoline/air mix, where the two are intimately mixed, does indeed have that sort of energy density. Gasoline by itself, nope. Which is why a tank of petrol is relatively safe. Fill a tank, drop in a lighted match and you'll get a pretty flame in the filler pipe. Do the same with an empty tank, where there are plenty of fumes, and you'll get a bang, but not much of one because the fumes don't have a lot of gasoline.

Despite what Hollywood wants you to believe, cars don't explode unless they are first subjected to the sort of abuse that creates a fuel-air mixture.
