Those UIs are made by embedded software engineers that have been in the automotive sector for 40 years. They have no clue how to make a modern functioning UI. The company then hires a UX expert that draws out a full plan. The software engineers implement it, it looks identical to the UX specification… but occasionally drops to 10FPS.

Probably because an important message passed by on the CAN-bus and that got a bit more priority from the CPU than the GUI

I think IF they had hired embedded software engineers with 40 years of experience, those people would have delivered a UI that meets or exceeds all UI needs (even if it didn't look as visually appealing as it could). A 40-year embedded veteran knows how to write real-time code, structure the system and make it work under all conditions.

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

CPUs do not talk to displays via CAN.
