There is no such thing as EMP. The resident FR EMP experts will be along shortly to explain.
Too late, they’ve already appeared...
In their experiments, a few cars stopped but started again immediately. If you have an electric car and it's plugged in recharging, it is fried. An EMP goes into the electric grid.
I am ready for an EMP since it is just like a hurricane coming through - power is going off. Power going off doesn't bother me that much as I have replaced electricity with other methods of power to have a fairly decent standard of living (no, I don't have a noisy generator that uses gasoline or propane).
I think it is likely our grid will be taken down in the not distant future. I expect it every day therefore I don't have to dwell on it - if it happens, it happens and I'm ready to deal with it. (Did I mention I have 10 ways to cook? Did I mention I will have running water when there is no any running water?)
