Re: Why terrifying?
Depending on the EV you buy somewhere between 3 and 4 miles per kwh of electricity is typical.
A 32A (7KW) connection can supply about 56KW hours of electricity in an 8 hour overnight charge. This will provide somewhere between 168 and 224 miles of range. While I am sure there are some people that need more this will provide for the *vast* majority of use cases just fine. If you need more then some cars can charge at 11 or 22KW on a 3 phase connection. If you only occasionally need more then DC rapid chargers exist with maximum supply rates between 50 and 350 KW of power depending on charger model, and car, typically allowing an 80% charge in 20-40 minutes.
While there does need to be improved numbers of rapid chargers they exist at motorway service stations and many major junctions so long distance travel is quite possible.
I have read studies that suggest over 80% of car owners have off-street parking so the majority should have no issue getting a home charger fitted. Obviously more provision will need to be made for streets of houses without drive ways.
