That article seems deeply flawed to me. With the cost of gas dropping to amazingly low levels, the tipping point is likely so far out that you'll never recover your extra cost for going electric. The countries mentioned in the graphs are spending a ton of money to force electric adoption and I didn't see that addressed. Those are dollars that could be put into infrastructure or other needs.
The battery technology still needs improvement and any new technology is likely more than a decade out.
