So we get our groceries delivered via a self driving car companied with a grocery chain in the Scottsdale Arizona area. If you want to know specifics, a simple google search will reveal both companies.
So the self driving car has two passengers. These guys dont pick out the groceries, load them, nor get out at delivery. We unload to the curb and they pull off. There is a $16 charge, the grocery store currently reduces it to $5.
Would you tip the riders? I had planned on it, but they didnt do anything, so i did not, and have continued not to. I feel a little awkward about it.
