> to become proven the AV needs to drive somewhere for a while.

There's a straightforward solution to this that doesn't compromise public safety:

Employ paid training drivers who monitor the AV while it is collecting training data in environments where it does not yet meet the safety bar. These drivers are paid to be observant and intervene to avoid accidents. Furthermore, in their interventions, these training drivers provide critical training data used to improve the system.

Uber did exactly that and got excoriated when the paid driver was on her phone and the car killed someone on the freeway. I think many people raising are concern trolling this because they either don’t want private cars in favor of public transportation or because they are luddites towards automation of driving jobs.

This is what Waymo does also.

Perhaps Uber should have been more careful whom they hire, or put stronger controls on what they are allowed to do in the car.
