And a real weapon can be used to remove the control on the traffic flow.

Well, maybe not. Suppose it's as simple as control over traffic lights

computer system to control them is probably networked and spread out all
over Saudi Arabia, and the lights themselves are quite numerous. Take
out the lights and you have gridlock.
