german auto companies aren't that competitive in ev field and i'm not sure they want to. Thousands of ppl are working at those and that work is related to combustion engine design, switching to ev might mean a huge blow for them. Nuclear, if done like in france/japan/korea, means cheap(er) reliable electric energy which would motivate more ppl to switch to ev's and since there are other players like tesla (more popular) or something from byd (cheaper) german auto industry can be in a tough position.
the interest in ice vehicles is either smaller and smaller lobby from them or the countries had little natural resources and national interest was put first, but who knows
Keep in mind that I'm stupid in politics and economy and I did not invest meaningful time into studying them, but:
I think generally accepted nuclear power is a literal threat to the German automotive industry.
MB, VW Group, BMW, and others are not ages ahead of Chinese manufacturers in EV sector like they are in case with ICE cars.
