I paid £1.45 a litre on Friday my average, which I tend to treat as about 14p a mile or 18c a mile.

I’m not sure why I’d deliberately burn more fuel regardless of the price. Literally setting fire to cash for nothing.

That would be $120 for your trip to Georgia, about the same price as in the US despite fuel being $7.30 a gallon equivalent in the uk.

I don't know where you're coming with deliberately here as if that's something I chose. I'm not familiar with cars getting 43mpg in the US. Maybe some hybrid, but that's definitely not the norm on this side of the pond. Even when I had a Corolla, which was the highest rated car I've ever driven, did not get 43mpg.

Your "deliberate" sounds a lot like victim blaming here.
