This seems a little weird to me. Modern drones are pretty much autonomous vehicles that receive behavior suggestions from their controller. Unlike cars and airplanes, they don't continuously rely on reaction times to stay in control.

Yes, a drunk person could pilot a drone into something, but it takes some effort. A drunk person could throw a rock at someone, but we don't ban drunks from carrying rocks.

This law would sound more compelling if there was a rash of drunken drone injuries.
