This has an odour of misrepresenting statistics.
I’d fully expect half, if not more, to have a 2nd car that isn’t an EV. Not as cover for long distance driving but because the two adults in the house work separately. One can take the children and go to work via school/childcare, the other straight to work. That’s not anti-EV enough though.
For a multitude of reasons, most families will have one large and expensive car and one smaller and, probably, older one. They are also unlikely to use the latter for holidays/long trips as it’ll either be less reliable or unsuitable for taking the whole family far. Now add in that the first car is an EV and nothing else changes. Unless you’re wealthy enough to afford 2 new cars every 3-5 years, one car will be older and cheaper and the other newer, more reliable and usually bigger. That newer, bigger vehicle takes the whole family away, the other takes one family member, possibly with a child or two, on short trips. Only those who are buying 2 cars will have one large and expensive EV (potentially thanks to a Salary Sacrifice type scheme) and one cheaper, smaller EV, and they’ll be few and far between, not because of anything EV related other than the up front cost and anticipated depreciation as it’s currently viewed.
What I’d like to see is what that picture looks like with various break downs, like both parents working in companies with Salary Sacrifice schemes or both with PIP and Motability or anything else that provides a reasonably priced option to get into the right position to be a dual EV (or more) family. Even down here in Cornwall, I know of one household where the parents both have EVs, one Tesla and an ID3, the son has just passed his test and has a Leaf 40, which has enough range but was a pretty cheap option. I also know entire housing estates where there’s nobody in anything newer than 5 years old and most cars are 10-15 years old and pretty knackered.
I'm Autistic, if I say something you find offensive, please let me know, I can guarantee it was unintentional.
I'll try to give my honest opinion but am always open to learning.
