I've had a dude with a Tagalog accent take over the speakers in my car and asked me and the folks I was inside with to leave because I decided to clown car it with friends visiting from out of state. With that said, there for sure is someone monitoring, but it's similar to how checkout at Amazon Go stores went.
I'd be curious to know how this monitoring scales over time.
