The lack of gas is not an issue in an immediate issue with an EMP.
If you assume that 90% of vehicles would stop workingin a worst case scenario, then you have plenty of gasoline for months for the vehicles which do work. A mathematical example:
A town of 5,000 people where there are 5,200 working vehicles would lose use of 4,680 vehicles in a worst case scenario. If the average fuel tank for those vehicles is 20 gallons, and the average tank is at 40% capacity, that would mean that the people of the town would have access to 37,400 gallons of gasoline for the 520 working vehicles.
Or (at an average 20 gallon tank) about 3 1/2 fill ups per working vehicle.
With proper rationing and judicious use of vehicles, you would have months of gasoline available.
Pardon me for my ignorance, but wouldn’t that be true only if the gasoline available was already pumped out of tanks before losing power? Say stored in 5 gallon cans or whatever?
Don’t know why I concern myself with hypothethicals but I find the subject frightening and certainly not beyond the realm of possibility. I’m not likely to understand your answer anyway but thanks.
