Excellent article and a first bite at the electrified economy issue !
As for the political establishment and their voter base implementing such a revolution in infrastructure - it will NOT happen by 2040 or any other time frame pronounced from on high. The related STEM and economic issues are far beyond simple minded grand standing. Never mind restructuring the tax base from fossil to electrical energy consumption - that alone will be a wake up call concerning the true costs of EVs. Lastly such major shifts cannot be subsidized, they have to fly on their own merit. The only reason we can afford (?) subsidies at present is because our fossil fuel based economy has sufficient surplus to pay for them.
