Jokes on them - I thought they would take over last decade. More seriously, in their graph it doesn't seem like US electric car sales is accelerating. What gives?
The US government isn't very interested in pushing them (though this may change as it re-enters Paris and so on).
The US doesn't have the same range of electric cars available as Europe or China. There's no US equivalent of the 20k VW e-up, say, or the Renault Zoe. This will likely change.
The US is much more sparsely populated than China or Europe, and average journey lengths are longer. This makes cheap electric cars with small batteries, in particular, unattractive. This is harder to change.
Electric cars are also somewhat politicised in the US, caught up in a culture war. This is essentially unique, and who knows whether it'll change.
We should expect China to have the most EVs since the CCP is basically mandating it.
Americans barely wore face masks. The government will literally have to print trillions again and give tax credits to get a mandate out to the public (our weirdo American capitalist version of CCP mandates at this point).
They're probably around. But I don't see them, so I don't know that they're around. This definitely makes me more cautious about getting an electric car.
We own a house, so we can put in an electric charger, but that would mean parking inside our garage. The problem is that our garage has been taken over by storage (working on that problem) and my woodworking. And when we do park the car in the garage, it's hard to get around the washer/dryer to get into the house.
We've already decided not to park the car in the garage except during big storms.
So even though we should be able to charge at home, we couldn't really do it well.
There are a ton of problems with how things are set up for the majority of people in regards to charging EVs. There's a lot of momentum to overcome.
What you'll end up doing is just buying one of those outdoor-rated extension leads that you can find in a gardening store and running it under the garage door out to where you park the car.
For now. As fewer people need them, that will likely change.
And eventually there will be so few gas cars on the road that "gas" stations have to be something else. It won't make economic sense to haul that fuel to as many places, and many will close or repurpose.
