Compared to all prior Model S/X, the Palladium (a.k.a. "refresh") S/X has software that is lacking in features and appears unfinished. My 7-year old Model S has more functionally complete software than my brand new Model X.
If you're coming from a 3/Y you might not realize it to the same extent, mostly because those cars don't have an instrument cluster display.
We can only hope that we'll eventually get feature parity with the prior generation cars. Someone needs to tweet at Elon and ask why the software for the flagship model Teslas is regressing in functionality and when they'll have equivalent functionality to the older cars.
