Interesting comment. These things can be turned into an unmanned self driving bomb. Take a pickup and load it up Timothy McVeigh style and send it off. This would be a terrorists dream, or an enemy such as the ChiComs. They could take out every major building in DC from Peking.
I don’t think you are the first to think of this, for terrorists and the Chicoms and who knows who else are several steps already in that direction.
Pronises, promises....
