I see two approaches, which allow different play options.
Option A:
He has one main drone which facilitates RP. Just like the car, the cost is therefore GM Fiat and not starting cash. In that case, make it a Stalker drone (not primitive) with environmental power mod. It then has a range of 2 kilometers, 5 hp, and no power requirements to impede play. He can pick two other mods to address how it can interact with scenes.
Option B:
Keep to primitive drones, but he has a large supply of them. He can participate in more than one scene, and have different capabilities per drone (but only one per scene/choice).
I don't see that all TL4 cities jam all drones. Where's that reference? What I do see is that control is jammed by ECM, which is a wide-area burst effect (not a constant effect). ECM is on all spaceships and also on Mechs, and can be in fixed city defenses, but is not practical as an "always on" as it scrambles all beneficial tech. I suggest it is safe to assume that the drone works until the GM intentionally fires off an ECM for plot reasons.
We should clarify if the VI operates like a human controller or like a cyberware bot-wrangler. As the former, he gets only one Main Action across both his forms (but both could still Move) and can control only one bot. As the latter, he can have main actions in both forms (sacrificing the car's move instead), can see through the bot pretty freely, and can control troll more than one drone as he levels up.
Drone Control Link: Most often found among military
bot wranglers, civilians can also get a drone con-
trol link implanted to simplify the remote piloting
of drones and other robotic units.
Users of a link can issue commands to a drone
as a Move action instead of a Main Action. A
single drone can only receive one command per
round, however.
Aside from this ease of command, someone
with an implanted rig can “look” through a piloted
drone’s sensors as an Instant action, and a drone
is never considered to be out of control even if
the pilot doesn’t spend an action controlling it. A
link can maintain a connection with one drone at
a time, plus the user’s Program skill.
