In a SHTF situation, you can’t even barter, borrow or steal electricity unless it’s with a generator and some gas.
So, you are stuck. It’s just easier to BBS the gas than it is to BBS gas for a generator.
It’s like I really want 50 million Americans with their little EBT ECars out there getting electricity supplements for charging their eHoopties.
Nope, they can keep them.
Not to mention that the electrical grid cannot handle 50 million electric cars plugged in all at once.
