No one is driving an hour out of their way for groceries.
And even the F150 truck example: if they are driving 30 miles to work, but 10 miles to Costco and 25 miles to home (Costco being 5 miles out of the way.), that F150 going 5 extra miles is more efficient than a Prius driving 25 miles from a Costco to their home.
Integrating routes throughout the day that matches your driving habits is a basic adulting task that everyone does, and has reasonably high efficiency.
I'm surprised you don't know any inefficient people! I know many. A friend drives 15 minutes out of the way because that grocery store is a little less crowded (they're the same chain). They've probably been doing it for a decade.

but that's not what's happening, Amazon isn't driving a Prius to your individual home then back to the warehouse... it's driving to a hundred people on an algorithmically optimized route. They do this because efficiency at scale makes them more profit.
Individual people make inefficient preferential decisions all the time, because the incentive to measure and improve these things is too low to bother on an individual scale.
