alt Hacker Newsthis isn't even close to true and falls apart in a number of ways, the most popular vehicle in america right now (F-series truck) is woefully inefficient for just about everything
there are people who regularly go out of their way to drive to their favorite store for like 1-2 special items, people bring their dogs along on trips for companionship and leave them sitting in an air conditioned idling car while they shop
individuals are irrationally inefficient in dozens of ways that large businesses root out, for better or worse
Special items they can't get off Amazon, I presume? So they need to take that trip anyway.
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.
