In seriousness, you're not going to get a very valuable answer with such a broad question. They can be quite cheap, but have little range. Elaborating on what you'd want in an EV would help people provide better answers.
Hmm, I've found it quite noticeable. Perhaps turn an FPS counter on and see what it's actually running at. If you have a game showing on both screens, it'll likely limit the fps to suit the lowest display hz.
The American data is also not fit. A part of a reduction in firearm deaths is advancements in medical treatment for bullet injuries. The actual statistic that should be tracked is bullet injuries, which is also quite incomplete due to many PDs classifying a survived bullet injury as an assault, limiting the ability to get accurate numbers on how many bullet injuries there actually are.
I've noticed Invidious instances having trouble recently as well. I'm sure they're not dead though, just need to get the next mouse for the endless cat and mouse game.
Also terrified of the same with my 9 month old, but you're right, my Ioniq also gives a reminder to check the back when the driver door is opened if the rear doors had opened prior to the drive. I hope I won't need it but it is nice to have.
Unfortunately there isn't really an all-in-one guide. TechnoTim has info on the Pi-hole config side and wildcard certificates, but I think he uses it with traefik.
NPM is pretty straightforward. If you find a site isn't working, try turning on Web Socket support.
I'd say just search for guides on each part individually:
Get all the services installed and up and running
Get SSL certificates from Cloudflare for your domain.
Set up NPM for the services you want to reverse proxy with your Cloudflare SSL certs (they wont work until the next step is done)
Set up pi-hole to be your local DNS (there's also adblock lists to add) and configure it to send all service(.lan).mydomain.com to the ip of NPM.
I'm definitely not a network pro, but it sounds like you're looking to do something similar to what I have.
I've got nginx proxy manager as my reverse proxy with pi-hole for local DNS. All traffic goes through the pi-hole and anything going to mydomain.com has DNS entries pointing to nginx. I've set nginx up so service.lan.mydomain.com is for anything local and just service.mydomain.com for anything external with wildcard SSL certs for both (*.domain doesn't seem to cover *.lan.domain so add certs for both - probably because it's a sub-subdomain).
The Cloudflare tunnel can then just get directed to service.mydomain.com instead of the IP of the service.
An e-bike probably.
