I wonder if the problem is that they're trying to coordinate/optimize drivers and routes after the orders have been placed. What if they tried to coordinate before the order was placed? There have been many days where I would have been happy to eat food from one of 10 different places, and we picked a restaurant more or less at random. If a platform could coordinate my choice with the choice of 4 very close by neighbors, then they could send one driver to pick up maybe $300-500 of orders ($60-100 food per household) and give us some sort of discount. I would actually allow notifications from an app that sometimes messaged me to say "several of your neighbors have ordered from X Restaurant, which you've liked in the past. Do you want to order also, for a 10% discount?". Of course, if they bullshitted and tried to fake-it-till-you-make-it with the order momentum (telling 50 neighbors that several already ordered), that would be annoying and potentially fraudulent. But I would be happy to see a competitor arise and shift the coordination from delivery to ordering. It could make the business model work much better, and would also cut down on travel time, food sogginess, etc.
