Glad you recognise the up sides. In case you weren't aware, you never directly acknowledged the benefits of electrification in the Australia outback.
You brushed off all benefits, "over simplification", and focused on extreme cases. Although very valid concern for someone living in such situation, it is similar to EV fires, we are discussing this as armchair experts. We have very little to add.
In such extreme remote area, EV would not be the sole answer, it will only be part of their fleet, the daily driver. No one has ever said it is the sole answer for everyone on Earth. But as already been pointed out, the individual only need to worry about finding solution after 5-15 years of ban of new ICE sales.
However, it has also been pointed out, does it concern us? In a small country that the longest distance end-to-end is less than 900 miles. Almost never 50 miles away from civilisation. Here, EV is very suitable for overwhelming vast majority and should be adopted as quickly as possible.
