Where do Tesla make it out to be very bad?unless its an NMC battery keeping the car at 100% doesnt hurt the car nearly as bad as tesla makes it out to be.
In the forums, there is a lot of rumors that is not what Tesla say. For example they do not say that you should not leave the car at 100% for long.
The <90% daily and >90% for trips is probably because it save a lot of cyclic aging.
As for the OP question Tesla say if you need more than 90% its ok to set the limit higher.
If you need the full range (i.e. 100%) of your battery for a long-distance trip, you can increase the limit to the ‘Trip’ range (>90%) as necessary.
