Hey, Kraken, you can fly it.
Actually, it flies itself. GPS. You tell it where you want it to be, it goes there, stays. If you reach up and move it, it buzzes back to where it was supposed to be. It keeps itself right side up, rotated, exact altitude, and if it loses signal, it flies up, moves to where it started from, and lands itself. Unless someone deliberately flies over cars or people, everything is safe, and I generally fly it several hundred feet away.
If it's not windy, it's simple, and if it is windy, it just buzzes harder staying where it was put.
Unless someone does something thoughtlessly (I can't imagine... ) the cars are safe.
