Very well. It's much more enjoyable to own an electric vehicle in colder climates than a gas/diesel powered one actually, since you can let it heat up and defrost completely before going anywhere.
I’ve been traveling all across the US in an EV and haven’t had any issues with range in the winter. Colorado mountains during ski season, Wyoming, Idaho, Montana in the spring. The built in navigation routes you to chargers based on current conditions and I’ve seen minimal range drop.
They actually don't use the fund to subsidize it. And many policies were added overtime, which any managed economy should be able to do.

Meanwhile in Slovenia - here, have some subsidy for buying a new one and that's all. Figure out yourself about charging, specially if you live in an apartment.
And a lot of smart investment, see the UK for an example of a country that got a 50% share in the exact same oil fields and continues to run itself into the ground to pay oligarchs.
