I am giving an analogy. Street car on digital track is the first part of it. The remote control aspects are there as well. It is not "direct" remote control. It is like a drone. You give a direction and the onboard computers execute on it. Direct remote control is not possible because of latency. But it also seems that the commercial launches of these vehicles might be dependent on 5G networks being available (lower latency, better reliability) in which case the remote control capabilities will be greatly enhanced before launch.
