There are stabilizing fluids you can add that extends the life to years. If owners can’t be bothered to do that the car could be programmed to use fuel every 6 months to prevent the negative side effects (in the case of cars like the Pacifica PHEV and Prius Prime, this is what happens)
The fuel issue is simply FUD. I’d be more concerned about BEV and range anxiety honestly. In Maine, for example, some Tesla owners reported the range being cut in half, during the winter. Simply unacceptable.
There are also, depending on the state, still gas stations that sell ethanol free fuel. The station up the street from me sells it but it is about 20 to 30 cents per gallon more expensive.
