In Vehicles, a drone shouldn't need any sort of Control Station - all it needs is a computer good enough to operate the drone. Assuming remote operation, that's not much. Otherwise, you need one good enough to host the AI controlling the ship. The reason Spaceships requires a Control Room for automated vehicles is because the weight and cost of the actual control stations are a small fraction of the system's weight and cost - the built-in communications system is another small fraction, with the bulk actually being the attitude jets, control surfaces, etc (which Vehicles apparently made part of the motive system).

As for controlling multiple drones, that's a bit hairier, and depends on how you're controlling them and how autonomous they are. Do you control them like you control Master Chief in Halo, or do you control them like you control James Raynor in Starcraft? For the former, you need very little AI on the drone, but it's nearly impossible to control more than one at a time. For the latter, you need the drones to be mostly autonomous, simply taking orders rather than following exact commands. There's also the issue of if you're using physical controls or a neural uplink - the former is much more limiting. I'd say, with physical controls, you can't really directly control more than one drone at a time; controlling multiple requires both that they have decent AI and that you make some use of the Tactics skill. With a neural uplink, you can directly control multiple drones at a time, but are at -4 to all rolls per drone beyond the first. Compartmentalized Mind reduces this - each "mind" you have can control one drone without issue, and is at -4 to all rolls per drone beyond the first, but you can share the load - someone with CM 1 could control 2 drones without issue, 3 drones at -4 to 2 of them and no penalty to the other, or 3 drones at -2 to everything, and so forth.
