EV's may introduce new challenges for the grid, but when a country is unable or unwilling to fix that then all those batteries could also present an opportunity to balance that same grid using software.
The problem that they do not mention is that they have huge investments in engine manufacturing that are useless for EV's. EV's are much simpler technology, the only hard parts are batteries and software.
Switching too fast will make their existing manufacturing capabilities worthless, and this is what is really threatening them. That is also making EV's "expensive" to build for them (but not for Tesla, or anyone building new factories).
I think that anyone in a developed country buying an ICE car now is already throwing money out the window: a few years from now nobody will want it anymore, depreciation will be very high.
