Though yes, California does have the least non-renewable power generation. Can you say the same for other states?
Additional maintenance is negligible when compared to the price of battery replacement.
I don’t think there are many people making trips in their vehicle just for gas. With a gas station on nearly every corner you’re able to easily stop on an existing trip to refuel.
When the power grid fails due to a natural disaster gas power is all you’ve got. With the limited range you have, is it worth the risk to try to drive somewhere for power?
I’m not against hybrids provided you can still get a reasonable amount of mileage off the gas. But like you said, we need massive amounts of improvement on batteries before we’re ready for mass adoption and for EVs to really be a viable replacement option.
