Ish.
There's clearly a logistics problem here. 1-meal being delivered promptly on time scales poorly. But 15 meals delivered to 15 different people within 45 minutes is in fact, a net gain.
Alas, Doordash and Uber have gone about it in all the wrong ways. Its the drivers who double-book this process (ie: picking up more orders than they can handle), leading to inconsistent quality, cold food, late deliveries and more.
Its a legitimate model though. A more "proper" company that's doing this officially is Foodsby, where one Restaraunt makes a single delivery to 15-ish people in one trip at a designated time and location (usually within 5 minutes walking distance of an office complex. IE: One particular office building has a Foodsby drop-off point).
Everyone pays $2 each, the driver is happy, the restaraunt is happy (their personal staff deliver and therefore ensure quality food / hot food at the appropriate, predesignated time), and a ~5 minute walk for a bunch of office workers is a good idea anyway cause we're all sitting on our asses all day.

It double-benefits because professional chefs like doing ~15 or 20 of the same order all at once, its more efficient for them... especially if they can plan such an order ahead of time (Foodsby isn't offered every day for a Restaraunt, they pick-and-choose the days that they'll offer the service).
So the chefs can cut-down on scheduling if they're burning out, or they can plan ahead and offer more days if they know some days are lulls / they have extra freetime.
Doordash / Grubhub / Uber is almost malicious for everyone involved. There's some ideas of convenience to some people, but its not good enough for the overall environment. In contrast, Foodsby (and hopefully more companies that adopt that model) has proven itself sustainable, at least in my area.
