I think it really depends on how drivers get paid and some computer tech to arrange uber eat drivers accept the optimal request at that time considering the distance of restaurant, driver and customer; or maybe two or three orders on one route then driver could deliver in just single journey.
Also, one thing I want to mention is that in China, although it's not 'uber eat', there are special restaurants opened just/mainly for take away and they are located together. So driver could only wait in one place and saved the time for driving to restaurant, and don't need to worry about orders, because there are enough 'take away' restaurants for him.
