What will be the effect of an EMP attack on electric cars that are supposed to be so good for us by getting us off that terrible oil?
If it is powerful to fry electric cars it will also probably fry the computers in gas ones too.
In that case only cars made before circa 1992 will work. (This was a plot point in the Tom Cruise version of War of the Worlds.)
Probably minimal. It’s not power systems that are vulnerable (I mean the actual power transmission, not the electronic control thereof), it’s the electronic control, and gas vehicles have more than enough of that to be rendered inoperable if they were taken out.
They would shut down any car made after, I think, 1972. That was when circuit boards started going into cars.
