Just because you might have a different experience doesn't mean this is US centric. The same happens across Canada and in several big cities in South America.
Many big US cities really aren't densely populated. e,g, including 2 of the 4 largest: LA & Houston.
I ... think I'm calling NYC part of the "civilized world" and I'm not sure how to feel.
I remember seeing a map of the US denoting whether the majority of commute was done by personal car vs public transport. The entirety of the US was by personal car… except for NYC. It had a bit of an Astérix feel to it.
I used UberEats once (in Sydney) because I had one of those coupons. UberEats was garbage. Cost too much and I could have gone to the place myself and returned in half the time.
I can’t advice beyond that but Uber is awful awful awful. Every time I give them a chance I regret it, be it on price, support, ethics, quality …
If you think delivery is unsustainable because cars cost money, I got news for you: You live in a bubble, and it's the cars that are unsustainable.
Outside of the car-centric world of US suburbia, most of the western world is actually doing deliveries on scooters and ebikes, which are very quick to navigate medium-to-high-density cities and can do several deliveries per trip.
I've ordered a lot on Takeaway, at least once a week on average. The last time I saw somebody pull up in a car was during the COVID lockdowns, and I suspect it's because there was basically nobody on the streets.
The business model is broken, because car-centrism is broken. In the civilized world, things are ok.
Either way, fuck Uber. There's better alternatives.
