I'm wondering how long it will be before we start seeing Unmanned Air Vehicles patrolling the sky's for highway patrol and general police work. The US military have exploded in their expansion and use of UAV Drones , and I believe it will only take a couple of local or state governments to try in a sample trial ( especially where revenue raising is concerned), before we see everybody else jumping on board. Imagine drones with speed radar and surveillance cameras patrolling the sky's of major cities like Sydney etc. They are cheap enough to run.
