You don’t think that thing was a least a homage to the Nazi salute?

Not only that, Musk straight up decided to support Republican candidates who are vocally anti-environmental, anti-electrification, anti-incentives to shift consumer and industry change. He supported candidates and ideology that do not align with the buyers most likely to associate themselves with EVs.

You don't need to argue the intent of the salute; you can just see which candidates he supported and donated to.

(It's fine to debate policy on things like incentives, but that is at least part of the reason why we see China making big leaps here because the government has aligned the incentives with buyers and manufacturers to make electrification the default)

Unions and environmentalism are two orthogonal issues. I'm not sure how you tie those two together.
