Are there instructions/hobbiest forums for just that?

The profit margins on cheap cars isn’t high enough yet to introduce EVs at that price.

What price? OP does not talk about cost at any point, they only require specific features.

nah, it’s better for information integrity to reply in the language you understand imo, comments translated using translator services are very obvious anyway and some people are multilingual

Sure, I agree? Maybe there’s a misunderstanding here and I should add that it simply would never even occur to me to enter a conversation if I didn’t natively understand the language that’s being used.

I often reply under Japanese posts, and I always assume users will use a translator as I do, but maybe in the context of a Japanese this may look rude?

Can’t speak for others (obviously, as this is about individual etiquette perceptions) but I would consider it to be polite to only enter conversations with unknown parties in languages that the parties have shown to be capable of speaking and understanding.
Using a new language entering a conversation would therefore signal either familiarity (“I know they understand me”) or rudeness (“I don’t care if they understand me”) to me, I suppose.

Never take any risks to improve the world, that’s how things are gonna get better!

No, I don’t think I’d agree with that.

How do you find out about it? Try to view the threads while logged out and not seeing your comments, I suppose?

Whether to flee or fight isn’t a very useful distinction, I think. It’s a false dichotomy.

Fighting someone or fighting for something in a way that risks your life just isn’t a very smart way to fight. Obviously run when your life is at stake. When you’re safe, fight.

What’s a bad upvote?
