I don't need 120hz Apple-like design, but it's crazy how they can't even keep a basic 30fps UI running smooth. And they still try to throw in more and more bad running animations.
Probably because an important message passed by on the CAN-bus and that got a bit more priority from the CPU than the GUI
In fact I wager the OPPOSITE happened -- that they hired or outsourced software to people who have "web technology experience" and the UI and graphics architecture is a mishmash software stacks hastily thrown together (read: not architected).
Jaguar has a similar issue with the I-PACE where the HVAC system couldn't keep up with the knobs and would lag. A real embedded engineer who worked on real-time systems would know how to properly handle a quadrature encoded knob and NOT lag. A web-technology-first person who slapped something together using nodejs and/or Python would likely not know.
Compared with UIs made by Microsoft, Google or Apple which also "have no clue how to make a modern functioning UI".
At least those "embedded software engineers that have been in the automotive sector for 40 years" don't need 16 GB of RAM for a chat programm
It's core to usability at this point, though. They should make the effort.
Both my BMWs (one each of the last two generations of iDrive) do not in any noticeable capacity, nor did my 2009 one with what was then known as "professional" navigation.
