My guy, you might as well have said "If Goku got on the bus and hit you with a Kamehameha wave, that'd kill you too" for all it matters. Goku isn't real, and neither is this Acme villain you've invented who goes around dropping anvils on people's heads.
Have you ever been on a bus? Because nobody's bringing car batteries on the bus. They're not even allowed in the first place; no explosive, flammable, or corrosive materials allowed. You're arguing something that doesn't exist, and wouldn't matter if it did because in case you didn't notice we currently live in a reality where horses getting onto the bus is literally more plausible than somebody dropping a car battery on your head.
