I wonder if anyone has any incentive to make it so you can pay with cash like a vending machine. (I think some of biggest benefits could be for those who struggle to afford cars, but those folks don't always good payment options.)
It’s not even possible to summon one without a phone/app.
But would the extra complexity, hardware, maintenance and associated costs ever be worth it for very small minority of transactions that would only be able to be cash.
It comes with a bunch of extra problems as well especially around abuse.
Better off just implementing gift cards to be bought with cash. Or maybe that’s what op meant?
