I dont know if they have all the metal you want, but maybe Youtube Music. One youtuber has stated that he gets about twice as much per view from YT Music than he does from Spotify.

At 11V you are already damaging most lead acid batteries, especially starter batteries.

If you only do it a few times it will probably take it, but not much more than that.

When I have kids I will allow them to go on the Internet, but I will teach them about where to find good content and stuff like that.

They will ultimately have to learn how to do this anyway, so its better to teach them early.

And I dont want to completely block their internet access because their classmates will have it too and it sucks to be the only one who doesnt, you just dont fit in quite as well and arent able to talk about stuff from the internet if you dont know anything about it. (I am speaking from experience)

I think touch controls make sense in cars, but only for navigation and advanced settings, like for how long the headlights should stay on when you leave the car, should the mirrors fold when you lock the car, stuff like that.

Everything else should have a button.

Here in Germany most (German) websites use .de, so its definetly not unprofessional here.

I am also not surprised that .de is one of the most used country TLDs out there.
