I guess I don't have that much faith in Amazon's ability to prioritize the customer over themselves (i.e., prioritize routing for the least amount of driving, regardless of what is being delivered).

In your mind if Amazon was optimising for their convenience alone they'd just pocket your money and not bother to ever deliver anything? Because that would the most convenient option for them.
That's called fraud and isn't generally considered a business model so much as a criminal enterprise
Your assumption runs contrary to the core idea of Amazon. Customer experience is the absolute most important thing.
Can you give some examples of times when Amazon HASN'T put the desires of the vast majority of customers first?
