That's not teleoperation. Teleoperation has a human directly in the control loop, so latency and stability of the connection directly impacts the vehicle system's ability to maintain safety, because the input has to go vehicle<->network<->human to produce an output. What those blog posts are talking about is a different strategy called remote assistance where the vehicle remains the only thing in the control loop, but a human provides guidance to help the computer navigate itself. This makes the latency and stability of the connection much less important for maintaining safety. It's not unheard of for companies in the industry that use remote assistance to also have an local option for remote control (for things like lot operations and vehicle rescue events), but that's not part of routine on-road operations and it's usually limited to a <5mph limp mode where the operator is physically present.
