I've been using Tesla's UI from the original Model S up through the current Model X with its binnacle and single horizontal screen. I've grown accustomed to the newer interfaces and actually find them quite effective, except for the lack of CarPlay support. My driving style might influence this, but with the latest Supervised FSD software, the car mostly drives itself, which reduces the need to interact with the screen to mostly music apps. Other interactions occur mainly for setting up navigation or initial vehicle setup.
Everyone has their own tolerance for UI quirks, and what works for one car might not for another. Tesla has spent years refining their UI and hardware to match their vehicle's characteristics. Meanwhile, Lucid is on its second major UI hardware iteration and is really finding its stride.
This is very much a personal preference thing. I agree, after using almost any UI, you’ll eventually get used to it; but that doesn’t mean it has good UX.
Lucid has better UX, imho; it is better thought out, features are more discoverable, it has better affordances/signifiers, etc. Fewer features, but better UX.
Better, but not perfect. The toggle for switching drive modes was not discoverable until very recently. HA still had plenty of UX issues, especially during LCA. And so on.
The difference is I feel like where the Lucid UX is very intentionally designed, the Tesla UX is mostly just “put it in some textual submenu and you’ll eventually find it, maybe.”
That’s fine, and it’s just my opinion, and has nothing to do with UI (or the look and feel, vs UX, which I use here to refer to usability).
Your opinion may differ, and I have no problem with that. I would describe Tesla’s UX as geared toward “power users” who are already familiar with the vehicle, the controls, the features, etc.
But if you put my dad in one of the two cars, I guarantee you he’ll have no idea what to do in a Tesla, and he’ll figure out the Lucid fairly quickly, even if he’s just starting with the physical controls. (I’ve tested this, because I was curious)
