Oh, right becasue idiots think an EMP would stop most vehicles from running.
Only those with modern computer controlled engines and sophisticated antipollution technology. And unfortunately it will take computer run equipment to fix them.
So, basically, we would be in 1910 for about a month, then 1920, within a year everyone would have power again.
Unfortunately it isn't 1910 any more. Nearly all of the available equipment that would be needed to build or repair infrastructure relies on either computers or electricity. Steam power has pretty much gone out of style. It might take longer than you think, and 1910 might be one of the better case scenarios for a starting point to rebuild. By the way, how many horses, wagons, and buggies are there around these days? I'm sure the Amish will do fine, but the rest of us?
Would civilization collapse? no.
It would be badly damaged at best, and there would be large numbers of people dying. Think "New Orleans" after Katrina on a country-wide scale.
EMP will likely take out most computer controlled engines, which is most modern engines. Supermarkets generally only have a few days of food on hand. Few people keep more than a few days of food on hand. A big part of that will start to go bad within a day or two when the electricity goes out and the refrigerator and freezer don't work. Cooking? Few houses and apartments are set up for cooking without electricity. In the dark, with limited food, difficulty cooking, coming problems with the water supply, there will be medical emergencies that will go unanswered because telephones won't work, ambulances won't run, the electronic health records rely on fried computers. Feel free to continue the exercise.
The internet would be running at some capacity through the whole thing.
Not if the EMP damaged the electronics, no. It certainly wouldn't have the major enabling role that it does today. And the "just in time" style of logistics that has become so common means there is far less slack in the supply chain than there used to be.
The biggest risk is that all these ignorant survivalist cause people to panic becasue of all the FUD that have been spreading.
You mean that the people that have stores of food, medicine, and essentials that operate without electricity will cause panic in the people without food, water, medicine, transportation? You might have that backwards.
