We do know our current infrastructure will handle ICE needs because it's been doing it for decades ... it will need considerable improvement to service the needs of EVs ... if a gallon of fuel requires the electricity to carry an EV 20 miles and as most average ICE cars do approaching 50+ mpg then it will take over 2 times the power to service their EV replacement ... with 'non-transport' electricity useage staying the same (and likely increasing as oil and gas are phased out of the power-hungry heating market) that's a whole lot of extra infrastructure and generation to find.
I too have seen these magic blanket videos .... are they really electric car fires or are they ICE being passed off ?... I understood that EV fires produce their own conditions for combustion and the only way to deal with them is to flood them with so much water they eventually drop below the heat requied to sustain themselves .... just partly cutting off the air with a blanket won't cut it like it will with an ICE fire.
