Tell me more about how I somehow gave consent to that. Also, tell me more about how a stranger holding a random found device authenticates a caller as the owner of said device.
I inferred that you discussed this with the person, since you indicated you talked to them via voice. That would have been the perfect time to arrange for return of the device.
I guess after reading between the lines, this person didn't suggest this action during the voice call, only via the text you discovered afterwards?
Elsewhere you mention that leaving the phone in the car was the best course of action, but the next person in that waymo could easily have swiped it.
I suppose a middle ground could have been to tell them to put it in the back seat pocket or something so that it was a bit more hidden while you contacted waymo support to let them know to retrieve it.

This is a little much. That's quite a threat model you are operating under. It explains why you immediately wiped. I think most people are not concerned with that contingency.
Why? I am a Waymo customer. I left it in the car, and so the service has a policy to collect the item and return it to their customer. Some random store where I don't go, all bets are off.
I was able to contact Waymo and discuss the lost item and they were able to recover it because it was left in the car. That is a success. I was also able to retrieve the item from their Depot because their Lost & Found process works. That is a 100% success.
It was unclear in my original comment, but the passenger's offer to leave it at a pharmacy was in a text message to my emergency contact, who didn't reply. I heard about that bit after-the-fact. All I told the passenger, repeatedly, was, "please leave it where you found it in the car" because Waymo would be able to work that out with me, a customer.
A few months ago, I lost the front door key to my apartment. The leasing office was closing in 5 minutes. I needed a loaner key, and I had no ID. I offered to leave my phone (one in the same) as collateral. They were extremely reluctant to be holding on to that instead of an ID. They said they'd make a one-time exception.
Phones are not really things that strangers like to hold on to, in case you've not noticed. If you are admitted to a hospital or jail or something, they get really jumpy about putting your electronics in a locker. Partly having to do with the likelihood of fire or explosion, the volume and value of personal data on those things, and their trackability. The best course of action for a lost device is you leave it where you found it, because that's the owner's best hope of retracing their path and finding it again.
