Y’all are not going to convince me!

No count down? No problem … throw a warning light and let me use the tripmeter without changing the display. Why would I care how many miles I have traveled before walking? It is just a distraction. BTW, just curious: what other manufacturer(s) use the count up?
If you don’t notice exactly when the reserve light comes on, the odometer won’t help you. If you reliably reset the trip meter when refueling, then you can use that with your normal range expectations, but if you neglect to do so, having a counter when on reserve can be helpful and gives a second reminder you are on low fuel. In any case, it’s a couple presses of the menu button to switch off the reserve mile indicator to your trip meter.
As to other bikes:
FJR has similar reserve counting miles since low fuel light. I’m sure there are some other modern fuel injected bikes that have it
Older bikes have a reserve petcock that needed to be switched when you “first” run out of fuel. You know you need to get fuel soon and similar to R18 most have a ~1 gallon difference between reserve and empty
Fuel injected bikes without a fuel gauge or reserve counter (most current bikes), you better hope you remembered to reset the trip meter when you refueled since you otherwise have no idea how much range you have left
Fuel injected bikes with a fuel gauge but no range indicator - Good luck, the gauge is accurate only 2 times per tank (when full and when empty)
Fuel injected bikes with remaining range indicator - Good luck, the gauge like a fuel gauge is mostly useless on a motorcycle as the fuel level sloshes around a lot (accelerating and braking, turning), so those 40 miles of range might only be 4 miles. Some bikes try to dampen this reading to avoid wild swings, but have fun walking when you rely on them.
