No, there was a test not long ago on vehicles with respect to EMP exposure. Most of the modern computer managed vehicles stopped running, but they essentially just got a scrambling and “rebooting” by removing the battery cable for a minute or so and reconnecting enabled them to be restarted.
I guess I should hunt the link up for that. It made sense too, as the sizes and lengths involved in an auto apparently aren’t amenable to building up really frying level voltages.
Thank you. I had read “One Second After”, and thought that cars would be unusable. Good information.
