Interesting that European makers are staying with petrol and diesel as Jaguar are not going to sell any petrol or diesel cars right now. They will no longer be made. Then, Jaguar will be EV only making a Toyota Aygo a car with much faster journey times to places 200 miles away and especially if lights, wipers and heater are needed which lowers range to 100 miles.
I did ask EV seller in Exeter if they sold any of these high end EVs and they rarely sold any and asked me to make any offer for one. They agreed a 20,000 pound discount on 2 Brands. The Volvo version was not worth an offer as its 60 mile range on a cold wet day made it unusable in Winter.
We will get these cars in the future though and maybe towing a solar bus behind it to charge.
Of course, EV cars will end all caravan towing as they are not capable yet
