[1] My current vehicle can do 800 miles between the 10 minutes it takes to fill it up, how long in total does it take to charge your BEV for 800 mile use?
There are always a few people who seem to have a genuine need to drive for hours non stop all the time, and you might be one of them. Sadly no EVs is going to fit you demands for a while, even the brand new £140k Mercedes EQS will 'only' do a realistic 350-400 miles with its massive 120kWh battery.
But most families don't use the car like the way you are suggesting. We've do 12k per year in our EV, take it on holiday/abroad and a range of 200 miles is more than enough.
Ofcourse the more miles you do the easier it is to justify an EV. Petrol seems to be approaching over £1.40/l and diesel £1.50/l. As much as electricity costs go up fuelling an EV remains cheap, and the more miles you do the better it is.
The biggest issues with EVs at present remains cost. Its sad to see Tesla constantly increasing prices, as other brands will see no doubt follow.
