It all depends on usage , if you have 20 km commute and 400km range , charging at home is irelevant as is the weekly overhead in visiting a fast charger , whereas I had a 130 km daily commute and relied heavily on nightly domestic charging

It's actually quite the opposite of that. If you have only a 20km commute then you can easily charge at home with even a little 120V 15A charger, no need to even install a 240V 30-50A circuit for higher power charging because you're only draining a small portion of the charge every day. If you have an exceptionally long commute or need to take a particularly long trip then you'll need faster charging to be practical. Tesla has said so themselves, the supercharger stations are intended to be used when you really need to charge up quickly, most charging is intended to be at home. Have you ever actually spent any time driving an EV? From what you say I suspect not, because if you had, my point about the home charging would be immediately obvious. As I said, every single person I know that has an EV charges primarily at home, every one of them, 100%. I don't know why someone would buy an electric car if they had nowhere to charge it at home when fuel powered cars are readily available and a bit cheaper. You just don't seem to get it and I don't know why this is a difficult concept to grasp.

You make it sound so easy but having a BEV ready to go at all times, means you need to plug it in (&out) all the time. That isn't an improvement in a time where modern cars have features like keyless entry where the number of things to do before driving away gets minimised.

At one of my employers one of my projects was an instrumented car that could also run the computers from mains power when the engine was off. Easy when it is parked inside where you certainly can do without the exhaust fumes. To me having to plug it in & out every time was a nuisance and more than once I drove off without disconnecting it first OR forgot to reconnect it. Fortunately I had made the mains connection using a plug that would prevent any damage from driving away with the mains plugged in.

The key point here is that making sure a BEV is ready to go whenever you want takes planning in advance which is much harder to do in a busy life compared to taking care of a car when it is actually needed. When I take a trip with a car (long or short) I don't fuel it up the night before. I do that along the way. There is always a gas station along the way and it takes a couple of minutes at most; not worth to put in extra planning effort. There is enough other stuff to plan.


BTW: one of my recent purchases is a corded screw driver / drill that runs from mains power. I got fed up with having to charge the batteries hours before using my cordless drill.

I don't know about you but I do have to plan with my petrol car. I often find myself visiting friends on a Sunday evening and have to consciously decide if I have enough petrol for the round trip and if needed buy petrol on the way (or the day before if I know I am going to be busy) because around here all the petrol stations shut early on a Sunday. At least charge points tend to be available 24 hours.

nctnico:
Over here the majority of the petrol stations are open for fueling 24/7 (many of them are unmanned anyway with a debit/credit card terminal). I very much prefer those because I can pay much quicker compared to going into the shop.

richard.cs:
Here even the ones with card prepayment at the pump tend to only be open when there is someone at the kiosk, though as I understand it unmanned ones are permitted. It may be mostly to do with the margins on fuel being low, most petrol stations here make the majority of their money in incidental sales (snacks, cigarettes, etc.) so there's little point them being open when "just" selling fuel.
