Yea, if even 1% of their fan base were to send them a message ot would be spam for days. Even if they weren't doing anything else it would be too much.
I went to school for electro-mechanics, electric drive trains are much simpler. The electronics have a couple of details, but they are basically scaled up computer psu-s. Biggest problem for car manufacturers is probably designing a different car then the ones they made before. Bateries are the most expensive part and should degrade faster then the motors (decades), maybe even electronics (10 years, depends on design).
But yea cars have gotten too expensive in the last 15(?) years.
My grandparents had pigs, chicken, goats, etc. And my father has farm animals. I'v also seen larger scale farming in my country. It's not so bad as what you are thinking of, here is not the usa. I know of what you want to show me. Maybe go watch Clarksons Farm for a different view ? Do what you want either way.
As one who does not care if the food i eat has meat in it, maybe i can clarify why people react like this. It's simple: you make me feel like i'm some sort of a heartless, evil person for eating meat, i will make you feel bad as well. Eating chicken is murder ? We humans are omnivores, we eat anything. Meat is less efficient land wise, but is more efficient to digest. Morals have nothing to do with it, as we have long evolved to be that way.
If you want people to eat more plants; my advice is to make it a better option. I often make myself a 100% plant pasta sauce, but that takes 3x longer to do and doesn't cost much less then just grilling a piece of meat and cutting a tomato or two. Make cheap tasty vegetarian fast food stalls, cheap mini markets, etc. Calling people murderers will make some of them hate you.
PS I have a vegetarian friend, for over a decade i didn't know he was. Respect his decision, has nothing to do with me.
