Interesting... I wonder if getting paid for closing the door still requires you to be active enough on the platform... otherwise I imagine you'd have people signing up for DoorDash just to stand in front of popular places and "hold the door open" for people... $10-20 a pop sounds like a good hustle.
I think the implication was that people stand around places where waymo goes often and just hold doors open for arriving waymo's to be "helpful". When the passenger leaves they just leave the door open for their doordash friends who are nearby
