And as someone who drove multiple cars, from multiple East Asian and European marks, I suggest you try drive newer cars, because your opinions don’t match 2024-2025 MY cars from those brands (except for maybe MG, and Toyota, but both aren’t designed or sold for the driving experience. Toyota leaves it for their Lexus brand, and Chinese marks don’t even try to compete on that yet).
The Kia's we tried were mostly great (The EV6 felt like a cockpit though) - the EV9 was awesome but we couldn't convince ourselves to get such a large vehicle.
Not an EV, but I have a 2022 Kia Sorento with a fair number of weird software bugs-e.g. the sound from the navigation system randomly stops working and I have to restart the car to make it work again; the car tries to read speed limit signs using machine vision but its capabilities are too basic so it reads them incorrectly (in particular, conditional speed limits which only apply under a certain condition, such as at certain times of day, for heavy vehicles only, it will treat as absolutes)
Is their EV software better? Outside of cars, my experience with South Korean software hasn’t impressed me
I find the OS perfectly boring, and I like it that way. Most of the car functions has physical, clicky buttons. The one that doesn't are justified IMO (navigation, pairing bluetooth, etc.).
