Thing is, those multiple charger ultra rapid sites are being put in right now all over the country, I’ve seen a lot of ultra rapids come online since I got the e-2008 last July, there are lots in the planning stage & quite a few installed but awaiting the grid connection.
Instavolt we’ve seen come near the top in reliability & they take a debit/credit card, ZapMap allows you to filter by such things so there’s no longer any need to stop at an ancient unreliable Dale Vince Ecotricity charger, even that Shell charger can be operated with a free Shell Recharge RFID card or things like ChargePoint/Maingau/etc., cards that cover multiple companies chargers.
Yes there’s a gulf of knowledge, it’s a steep learning curve, but within a couple of years it would be the same problem for someone coming from an EV to a fossil, I no longer look for or visit petrol stations except when I saddle up the motorbike in summer (yes, I still have a fossil with an auto gearbox, but it’s my motorbike, and it has about the same range as the e-2008 before it needs fuel which is why it was so easy for me to adapt to an EV’s range).
