I'll reduce the problem to something falsifiable. You might prove presence or lack of neo-Nazis in EV industry leadership like this:
1. List all electric vehicle makers registered to trade in the US market.
2. List their top leaders, particularly the chief executive, operating, and financial officers.
3. Find political parties with a strongly socially conservative national-populist platform, such as Alternative for Germany (AfD, Germany), the National Rally (RN, France), and the Republican Party (GOP, United States). These parties tend to draw credible comparisons to the NSDAP. Add extra points for parties promoting natalism or eugenics.
4. Look for news articles in which a top leader of an EV maker has publicly supported one of these Nazi-aligned parties.
This procedure would identify Tesla head Elon Musk, who has spoken before AfD.
