EVs use more than an average home's entire daily electricity budget to go 50 miles. In an emergency you could run your lights, fridge, and water heater for weeks on an EV battery. It's really not much wear and tear.
That seems like a use that Ford is already embracing with things like the lightning.
My comment was more in line with using cars as energy storage infrastructure. I think most car owners don’t want to use their car batteries as grid infrastructure.
Cars are an immensely inefficient platform.
