Yeah, seems like there could be a point where the gas engine sufficient to generate an emergency charge could be small enough that the impact while non negligible would be worth the elimination of battery fear. The tank could be empty most of the time and just available for a quick gas station fill if on a long trip and battery prediction is insufficient to reach the destination. Alternatively fast capacitor charges or a small swappable emergency battery that gas stations could carry for evs seem like systemic changes that could help with this issue.
