Totally bonkers 'Miles to empty' on 2020+ Spyder - can it be fixed?

Out here in the mountain west of the US you tend to learn to fill up with gas where and when it is available when outside of major urban centers.

You are never quite sure on your particular route where the next gas station might be. I'm sure it's the same in Oz, especially when heading West to Perth.

Remember too, not all gas is equal with the same additive packages, even if the basic gas itself comes from the same bulk supplier at the refinery. I try to use Costco, or Chevron when I'm away from Costco. Costco is cheaper but very consistent with their additive packages, Chevron is pricey but once again their additive packages seem very good. Sunnoco is pretty awful from my experience. Maverick seems to be consistent at least and their stores are good.

Of course, needs are as needs must when out in the boonies.

Yes, I saw on the maps that fuel stops were quite away apart. It's like that out here in the mountain West of the US, I-70 through Central Utah has a 100+ mile stretch without gas, and that's a crazy uphill mountain climb heading West, so fuel consumption can drop a fair bit from that even before a strong headwind.

I also heard that the fuel stops on the road West to Perth can sometimes lose communications for accepting plastic. There seemed to be little choice for food or motels as well.

The US is about the same size in the lower 48 as Australia but with 350 million people. However, if you ignore the few cities within 100 miles of the Pacific ocean, the western half of the US geographically, contains only 15% of the population. I know that's still a lot by comparison with Australia, but if you exclude the frontal range in Colorado and the Wasatch Front in Utah, there's a whole lot of nothing out here, lots of prairie, tall mountain ranges, and salt flat valleys with little to no water. The entire state of Wyoming is just 250,000 people.

So, I know it's not like the Nullarbor, but ours is basin (valleys) and range (North to South mountains), rinse and repeat from Colorado to the sea side. On I-80 there's not much between Cheyenne, Wyoming and Salt Lake City, Utah, and then to Reno, Nevada, before the Central Valley of California. Like Adelaide, it's a good days drive to the next metropolis, North or South, East or West. I like the isolation though, being able to get out in the middle of nowhere so easily.
