You're dumping what is presumably the equivalent of several gallons of gasoline's worth of energy. That's a very large amount of energy. After all, a Fuel-Air-Explosive is nothing more than some hot gas... Gasoline powered automobiles don't usually explode on impact despite what you see in the movies. Flywheel powered vehicles seem a lot more risky to me. I hope they do lots of crash tests before unleashing such a dangerous technology on the unsuspecting public. Can you imagine the bumper stickers: CAUTION: FLYWHEEL ONBOARD -- My opinions are my own.
