You can control a vehicle or drone remotely via Augmented Reality (AR) using your meatworld initiative. Doesn't matter whether you have a commlink, cyberdeck, or RCC. This is basic Remote Control, essentially "video game mode."
You can also control a a vehicle or drone remotely via Virtual Reality (VR) using your cold-sim or hot-sim Matrix initiative. Still doesn't matter whether you have a commlink, cyberdeck, or RCC. This is more like what Letitia Wright (Shuri) and Martin Freeman (Ross) do in the recent Black Panther movie. This is still Remote Control, though, not Rigger Control.
You must be in VR before you can "jump into" a drone or vehicle. That gives you full Rigger Control, the next level beyond Remote Control. You also need a Control Rig implant, and (unless you're jacked directly into the vehicle) an RCC.
