I only have one at the moment. I bought a cheap Dell Wyse thin client from eBay, installed a light Linux distro on it and set it up as a Wyoming Satellite and as a snapcast client. That is connected to an old all in one mini HiFi for speakers. For the mic I just have a small omnidirectional USB mic plugged into the front. Biggest hassle setting it up was ALSA since snapcast and Wyoming were fighting over the devices

It's what Americans would call a band-aid

I can only speak for myself but the upcoming ICE ban was a factor in my recent EV purchase. I intend to keep my car for a long time so as we move closer to the ban more and more cars will be EVs so I didn't want to be left behind.

The other aspects you mentioned were also factors. Particularly after a test drive and feeling the acceleration and quietness of the car.

I agree that a mix of energy sources is a good idea. Maybe a mix of wind, solar, hydro...

Batteries isn't an energy source, it's energy storage. We can generate electricity in many ways.

Disclaimer: I've only had my EV for about a month and usually charge at work or home so haven't got that much experience with public charger etiquette.

I wouldn't think 4 hours a week is "hogging it" but I would think the etiquette somewhat depends what 4 hours you are there. If your 4 hours coincidence with the peak usage of the charger (maybe when people are checking in for example) that is different to 4 hours when nobody is there anyway.
