I rented a Tesla while on a business trip a few weeks back (not by choice, the rental agency just gave it to me in the Economy class) and I absolutely hated the UI. The basic car interface has converged on its standard form after decades of desiggn, and that means that when I get into most cars I immediately know how to adjust the various settings to my preferences. Having to spend 15 minutes sitting in a rental car parking lot digging through the menu at 1am just so I could move the wing mirrors and seat was an incredible pain. All the settings I care about were like 3 levels deep in some menu, and that sucks! Sure having a lot of knobs in view isn't as "aesthetic" from a premium product perspective, but damn does it make it easy to change things quickly.
