Try it for yourself - go into the screen and change your wheel type - you'll see the range on the guessometer change.
This is indeed the exact standard for the pharmaceutical industry today. Would be consistent consumer protection to have similar for EVs.
you want consistency between 2 different gov't departments? 2 different departments with different missions? and to have consumer protections as the lead when a third department is responsible for consumer protections, not the prior 2? and you want them to buck trends and standards of other sovereign nations and the EU?
I will assume you mean the consumption screen. Maybe this changes things, maybe it doesn’t (it shouldn’t, since if it did it it would screw up capacity method - though it changes the Trip Planner for sure). But in any case not what I was referring to, as you can see.
No, I was not suggesting unifying rules for pharma and EVs and oversight of both to be centralized at all. Just no. You clearly can understand the point, which is that I believe better consumer protection laws should and will go in place. Don't make an argument where there isn't one, or misconstrue what I said and attack your false re-interpretation.
in that case, i have no idea what you are asking the EPA to do, then.
I've always considered EPA MPG ratings as an "apples to apples" comparison for consumers to evaluate the efficiency between different makes and models, not a truth in actual real world use. The same applies for EV range. The test conditions should be identical so that there is a proper comparison when shopping between brands and models. There are simply too many variables in the real world to expect an accurate mileage rating that is one size fits all. You're trying to fit a round peg in a square hole - EPA ratings are about efficiency, not gas tank (or battery) capacity.
Unfortunately some multiply the result by 0.7, while others use 0.75, etc. So even two manufacturers with identical results could have different ratings. It is a choice. 0.7 is the default. But if 5-cycle testing is done, other choices are allowed, to multiply the two-cycle test results by.
The multipliers are specified, but car companies are allowed to report worse numbers than the test results if they choose (which seems to be why Porsche EVs have such poor EPA numbers but third party testers sometimes beat the EPA number by much more in Porsche EVs than other EVs -- perhaps Porsche assumes that its drivers will driver like Porsche drivers instead of EPA drivers so they do not want to disappoint them).
And can be variable, according to EPA formula and manufacturer choice.
According to https://www.epa.gov/system/files/documents/2022-12/420r22029.pdf page D-2 in Appendix D, there is no mention of manufacturers being able to choose multipliers, but "Under the 5-cycle methodology, manufacturers could either: 1) perform all five tests on each vehicle (the “full 5-cycle” method), 2) use an alternative analytical “derived 5-cycle” method based on 2-cycle testing if certain conditions were met, or 3) voluntarily use lower fuel economy label estimates than those resulting from the full 5-cycle or derived 5-cycle."
You can just look and see what they do.
No I'm referring to the battery icon at the top of the screen (which I think the OP was using - its such a long thread lol) when its showing remaining miles rather than percentage. It changes when you change the wheel configuration. My 2019 SR+ does this.
That is not a guess-o-meter in the sense that the term is usually used to describe a distance-to-empty display that takes into account recent consumption.
Shall we call it the never-right-o-meter then?
The rated miles display is basically a higher resolution state-of-charge gauge.
So you measure your iPad's utility in the amount of time you can use it on 80% charge every time you charge it? Or do you generally expect that when you charge it full you get a day's worth of use out of it and charge it again?
