Phantom Auto, mentioned in the article, demoed their RC cars in CES last month, and they were ferrying journalists around using a driver 500 miles away. Latency isn't as much of an issue as one might think, but to maintain network reliability phantom uses 5 different networks simultaneously. Waymo and Cruise (GM) are both building out call centres with agents that have some sort of remote control over the car. Both Waymo and GM have emergency stop buttons connected to an air gapped computer that can take the vehicle to a minimum viable risk condition (which basically means pulling over to the side of the road) for security.
