It is really difficult to read if this is sarcasm or not, and I am not being sarcastic.
But in this case it means the car now trusts you to trust it by not putting your hands on the wheel?
If you think Waymo doesn’t have thousands of people doing the same but remotely - I have bridge to sell you.
Any remote watcher can't be expected to avoid a crash in realtime.
Waymo is trusted to behave safely without supervision, but of course they monitor everything to validate and improve.
