I don’t think sending a couple drones to canvas a city grid from the sky would count as less useful. In fact, it’d be a lot faster than strapping a camera to a truck/car. Really depends how they are used. But worst case scenario, both drones and fixed cameras work in conjunction, which they obviously would.
A handful in the sky is still a lot less useful than the thousands on the ground. We need them off the streets and then we can deal with the drones.
