Speaking of power outages in a broader EV era…
Today we can fuel up at almost any corner at a choice of fuel stations. Less than 5 min from home in most cases. Short lines 98% of the time.
In EV world there will be a shortage of charging stations and many will not have home lines (low-mid income homes, apartment/ condos complexes etc.).
Further, it something happens or someone decides to cut power to a wide area - it's 'off the grid' for a time.
Of course the generation of green electricity could never power EVs let alone industrial operations and public needs (Subways lights in any city).
We have brown outs and black outs as it is with today's fossil fuels generating electricity.
Back to the key point - in a green energy landscape it will be easier to 'shut down' mobility - for those fortunate enough to be able to own an EV.
