They are ahead of Europe (at least in car UX) but quite behind of the US. This is the last stronghold that the US has but given the recent layoffs and transition toward "AI everything", I am not sure if the US tech industry will survive this too.
I would rate Europe over US by far for car UX. My north American vehicles universally have the worst interfaces. My European Cars typically the best and Japanese/others in between.
Time to start learning Chinese.
