A lot of consumer tech with very competitive UX is coming out of China. They are also getting very strongly into e.g. web frontend tech. I see no reason why the west would have any special advantage in this.
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.
