You can't do this with Uber/Lyft.

How do you even lower the quality - serve half broken car for a luxury order? No way person who orders luxury car accepts it.

Or do you increase wait times? - sure, order gets cancelled, you won't get a payment for that.

There are of course ways, but you still can do something, in case of LLMs, you blame yourself for poor prompting and retry, which again makes money to LLM providers
