Besides, if the power outage brings society into such a disarray that you can't just call an ambulance if something happened, then there is a high likeliood that having a petrol-powered car wouldn't be much better than an electric one anyway.
Europe is a big place, though. There's a lot of people living in the countryside and with much less reliable utilities compared to urban areas. Power outages do occur here too and they're even frequent in some areas. :)
Can confirm this is true for Australia. We frequently have outages and the network is in shambles.
Just to make sure, rather than provide any incentives (there are NONE) we're going to introduce extra taxes for EVs to make up for lost fuel excise taxes, which contrary to popular belief doesn't pay for our roads.
I guess the minimalist (by Norwegian standards) yet growing sales numbers in spite of our soaring electricity costs and Zero CO² taxes on ICEs (they're eg 40% in Norway) must be scaring the fossil fuel sponsored politicians (both Libs and Labor alike).
Here in Japan, blackout is very rare event but Leaf and Outlander PHEV supports V2H from first release. Normally it's not needed but it's helpful when disaster happened.
Just keep your car charged between 50% and 80% when you are at home and it should be enough to reach the hospital or a safe place during a blackout.
