Not quite a rational comparison because I am sure most people drive and refill with much more frequency than they go through black powder, and it's not like the last US manufacturer of gas just announced they are calling it quits.You don't wait till a gas shortage hits to fill your tank right?
Regardless it will affect some more than others, and those who 'have' to use real BP will have to adjust to the change and possibly resort to having to buy European powder.
