If you live in large parts of the USA, by which I mean pretty much anything that is not the eastern seaboard or California, and you need to go anywhere remotely rural, charging infrastructure is absolutely not reliable.
I have an EV, which is amazing in my metro area, but I regularly take trips where I would not feel comfortable finding a place to charge, despite what EV locator maps might tell you. If you show up and that charger is not working, which is not uncommon, you might be stranded.
What EV? I have a 2020 Model 3 and in six years I've never had an issue with charging, even when driving around rural Montana & Idaho in the winter. I've never had a supercharging station be out of commission. Sometimes an individual stall or small group of stalls will be offline, but the car tells you which ones are broken so you don't waste time trying to charge at one.
