I stopped watching at the point he says if the other 5 houses in his estate were to get 7kw wall chargers it would put a huge demand on the supply to his house
To discuss his other points, obviously charging from home is the best solution but the problem with videos like this is they never discuss the options you will soon have (see below) if you don't have home charging, the vast majority of us wont charge our cars like we do out phones we will charge as its needed not every day, i could probably get a fortnights motoring out of a single charge if i wasn't making any journeys i don't normally make and i imagine the vast majority of us are in the same boat.
Drivers who do huge mileages obviously wont be thinking of buying an EV until the range increases significantly.
