Waymo routinely uses safety drivers, sorry, "autonomous specialists" when expanding to new cities[1][2]. Waymo cars occasionally contact the remote support. If support is not available, the cars just stay where they stopped[3].
Tesla has rolled out a small number of cars with no safety driver[4].
In short, you are either grossly misinformed or intentionally lying. Is it a political echochamber you are stuck in?

These specialists are there to monitor our autonomous driving technology and share important feedback to help us improve the Waymo experience."
