What if there was a herd of people off-shore on-call willing to basically "RDP in" and take over control (human takeover) of the entire fleet when needed? I could see that being an attractive pitch.
I suspect that in a large scale disaster/emergency the communications systems may be disrupted and it may not be possible to remotely control the vehicles.
Perhaps in such cases they can pull over in a safe place, or if they have an occupant ask them if they wish to continue the journey or stop.
Perhaps they already do this, I have no experience with autonomous vehicles.
This very scenario could involve no cell signal.
Latency makes this hard even with local connections, it’s essentially impossible due to physics to do it offshore.
And I believe Waymo remote access only allows providing high level instructions (like pull over, take the next right, go around this car, etc) precisely because full direct control with a highly and variably latent system is very hard/dangerous.
And in an emergency situation you’re likely to have terrible connectivity AND high level commands are unlikely to be sufficient for the complexity of the situation.
