A 2022 Toyota Corolla gets around 40mpg highway and squeezes 5 people inside so it uses 0.5 gallons per person per 100mi.
5 people in the Corolla is 2–3 times as many people as are at all likely to be in there. That's a very skewed number.
When using realistic numbers, cars come in at about the same per mile as large commercial airliners. (Flights tend to be far, far longer of course.)
I haven't touched the thing in three years.
I just remember that it had pace where it should have average speed. That is all.
Now go away. I'm not interested in defending myself to someone like you, who's been nothing but nasty.
