Pizza Hut's AI system caused 'cascading' problems and $100M in damages, franchisee alleges in new suit
(www.businessinsider.com)
I don't use DoorDash but occasionally order from Taco Bell. Every time I order I watch the car arrive at Taco Bell and wait about 20 minutes before actually picking up my order and then delivering it.
Additionally I know UberEats used to (and maybe still does) offer cheaper delivery if you pick a restaurant another driver was already heading to. (I haven't used UberEats in years because I found them less reliable.)
Ironically if a restaurant did all the deliveries themselves they would have all the information about how best to optimize delivery. Maybe all the delivery companies can find a way to share this information to minimize travel and maximize speed of delivery.
