“It occurred to me recently ... the move to electric cars portends an even worse resulting scenario from any EMP....”
Not just electric cars my FRiend, but all cars from about the mid-80’s to present. That’s some fine engineering from all manufacturers. /s
Practically all modern vehicles are simply rolling computers with four tires.
Even earlier.
An EMP will weld the points shut on the distro and fry any magneto-spark igniotion.
