I regularly walk by one of their parking lots (14th St & Shotwell), which used to be typically relatively full, and now it's generally pretty empty. They're all out and about ... but on the other hand, a significant proportion of the waymo vehicles I see on the street are empty. I would be curious to see the difference in miles driven without a passenger per vehicle relative to Uber/Lyft. Are those empty miles about distance between drop-off and next pick-up? Or are they still doing a lot of extra miles just to collect data (e.g. going down streets that fares typically don't go down)?
