From elsewhere in this thread:

> In the first 3 quarters of 2020, Doordash has $131 million loss on $1.9 billion revenue

If a startup starting from 0 can pull that off, Amazon should have been able to do (even) better with their customer base and logistics know-how + infrastructure.

How is losing money a positive? Amazon should have been able to lose even more given more of an investment? Amazon realized its bound to be a big loser and left it.

Even the most conservative investors will look at a loss as a percentage of revenue and not in isolation. Decades of business experience have shown that a low loss ratio in a fast growing business is a good investment opportunity.

I don't see how Amazon's logistics and infrastructure translate to restaurant delivery. They can't stock orders in their warehouses.

Amazon has built a delivery network that is almost on par with DHL and others. I would say that's not only a pretty good starting point to get involved in restaurant delivery, but would also increase the utilization of the delivery vehicles (think Uber Eats).

Amazon's delivery network is built around pre-optimized multi-hour routes. Like DHL and others it's completely unsuited for restaurant delivery.
