Honestly, I love the UX and UI of a Tesla.
It automates so many things that I find tedious in other cars: lock/unlock, close windows, pre-heat/cool, auto-set navigation to office in the morning and home in the evening, set seating and other adjustments for the driver based on which phone key was used. Navigation works thanks to the free connectivity (all other in-car gpses I've had to use were useless). Nice screen to select and play music. Voice command works reasonably well for selecting music.
It's not perfect, but I prefer the UX & UI over all ICE cars I've driven before.
As an example: my user journey when starting my drive to the office in the morning is a 2 step process: (1) open door and (2) put in drive.
Especially in the winter that used to be 10+ steps for an ICE car: (1) find key (2) unlock car (3) open car (4) adjust seat because my wife drove before (5) press button to start engine (6) front-window defrost (7) rear window defrost (8) manually scrape the ice off the front window (9) select office in gps (10) release parking brake (11) clutch (12) put in gear.
