I know that this is a forum of EV owners so maybe this is a bit of an echo chamber for those of us who like EVs, but I’ve recently become aware of some very strong views from family and social media who sound a bit hostile to the arguments supporting EV ownership.
It’s the usual sort of things: ‘EVs are too expensive to purchase, only rich people can afford them. they cost almost as much to rapid charge as petrol equivalent. Most people don’t have the means to get a Type 2 charger at home, the charging network is poor. Where is all this electricity needed for EVs going to come from? Etc?’
There is a lot of truth, currently, to all these arguments. EVs are currently too expensive for mass adoption, even after government subsides, and those subsidies carry their own problems. Not only are the subsidies costly, in many cases they constitute a tax windfall for the wealthy. In many cases DCFC
does cost as much as gasoline. The charging network
is poor, even for Tesla, relative to gasoline. Home charging is
not easy for many people, especially in Europe. Where
will all the electricity needed to power a mass transition to EVs come from? Where will the
batteries come from? The truth is that we are
decades away from EVs constituting a majority of cars on the roads in most countries, even highly developed countries.
I think you would have more enjoyable discussions with your family members, and a more enjoyable time with them period, if you started by acknowledging that maybe you're not right about everything. Maybe they've got a point (they do). And even if you disagree with them politically, that doesn't make them stupid (there is no correlation between politics and intelligence). Comparing people who don't agree with you on EVs, or politics, etc. as "flat earthers" is the height of pretension.
Specifically with respect to EVs, I would not advise taking the "environmental" approach with your family because EVs are not particularly environmentally friendly. In fact, in some ways they are downright filthy. The "green" argument for EVs relies on a set of very rosy assumptions about the future of battery and electrical production, and adoption, that is a looooong way from reality.
The approach your family probably will respond to: EVs are FUN to drive! They're fast! They require less maintenance. You might even save money in the long run if you can charge at home.
