It always baffles me how people portray their opinions as fact. By no means would I say the UI is the best thing out there; however, I have no issue with it at all. I have had a 2015 S, 2021 3, and 2022 Y, I have had almost every iteration of the UI since 2015. I have owned Ford, Mercedes, BMW, Chrysler, Lincoln, Audi, and Nissan, I have driven multiple EVs, including the Mach E, Leaf, E-tron, Lightning, Taycan, R1T, Ioniq 5, so I have had experience with many different companies,...ALL of them could be improved, and Tesla is no different, but to state Tesla's UI/UX is subjectively awful is hyperbole.
Your opinion is valuable, and what makes forums such as these good, but you cannot force your opinion on others and tell them that it's fact.
