I can relate to your persistent questioning about all this. I, too, came from Teslandia.
Our newest Tesla Model X when brand new, and when charged to 100%, indicated 296 miles of rated range (published EPA rated range was 295). It stayed at that level for several days, before rated miles started dropping a few miles every week. In Teslandia this was one metric owners used to get an idea of their battery degradation.
Five years hence, charging our Model X to 100% yields 263 miles of rated range, indicating a total battery degradation of about 10%.
So, yes, in my Tesla, I display percentage rather than rated range almost all the time. But once in a while, especially right after charging to 100% I switch to rated miles, just to see (torture myself, really), how many more miles of rated range I have lost. In the end, even switching from percentage to rated miles stopped being necessary because of the plethora of Tesla-related apps that have proliferated, that readily give you that information. Not only do all these Tesla apps directly give you your rated range, it’ll even give you your actual range based on your driving “history” and your battery degradation.
To my knowledge no independently developed apps, offering so much car specific data, have been developed for Lucid.
In my Lucid, I’ve carried over the Tesla practice of keeping my display at percentage. I’m gathering from this forum that switching to “Miles Remaining” is even less useful than switching to “Rated Range” or “Ideal Range” in a Tesla because for one, none of us drive our cars like we’re trapped in an EPA five-cycle testing loop; and more pointedly, in our Lucids the Miles Remaining number doesn’t seem to change. Eight months and 15,500 miles after first taking delivery, my Miles Remaining display at 80% charge shows 426 miles, the same number that it was when my car was brand new. I have no indication at all as to how much my battery has degraded, how fast it’s degrading, or how many rated miles I’ve “lost”.
I understand the contention expressed here that “Available Miles” are imaginary miles or fairyland miles, and therefore not to be bothered with for determining your actual range. However, I for one would still be interested in seeing the change in Available Miles, and the rate of change in my Available Miles, because I can then use that as a baseline for guesstimating how many real world miles I have available. This for me, is an additional method, an adjunct to the method already described above.
Finally, in my use case where maximum range is king, I am keenly aware that the distance I am able to drive today between 90% and 20%, will not be the same as distance I will be able to drive between 90% and 20%, five years from now. In fact, all factors being equal, it will be decidedly less. Just how much less, I can only conjecture from previous Tesla owner experience. It will only ever be conjecture until Lucid offers us more information about battery degradation, either through what’s displayed in the car, or via the Lucid app.
