National Geographic has presumably explored the risk and consequences of the “electronic Armageddon” that could be caused by an electromagnetic pulse (EMP) bomb.
An EMP bomb, National Geographic explains, is “a bomb that’s designed to go above the atmosphere and release huge amounts of energy,” some of which in the form of gamma rays. Such a weapon would cripple electronics, but not kill people.
“In less than a billionth of a second, the electrical intensity on Earth’s surface would become so hot that microchips would fry, power lines would overload and the electric grid would collapse,” says National Geographic, describing . “Everything with microelectronics in it would stop: your car, your computer, the subway. There would be no electricity.”

I am under the impression only energized circuits would be rendered inoperable.
There are many vehicles with “primitive” type circuits, that only contain fuzes, whose only advanced component is a bridge diode. Would these surivive the EMP blast there would be a few vehicles on the road.
The best tools at your disposal are those with the fewest moving parts, they are easy to repair and maintain, and some parts can be built by anyone with an imagination.
