Electric cars are way way simpler than ICE cars. It's just market segmentation gone wrong when EU car manufacturers wanted to sell these cheaper cars as premium/luxury ones (i.e. greed) and therefore couldn't learn the lessons from producing them at scale on cheaper models. China had poor ICE cars and bet everything on EVs, scaled their production up, reiterated a few times, and now Nio/Xiaomi/BYD/Zeekr are better than anything built in the EU.
