No argument, it is possible to push the batteries to depletion. This is not a car for the driver whose prime focus is squealing around turns through the mountains without bothering to turn on the “mountain mode”, not the car for towing a boat with, not the best car for someone whose main focus is cross country car trips, not great for someone who needs to carry around three of four kids under ten years old, not the vehicle to use as a garbage truck or a snow plow, and it will not do my taxes for me either.
It is not a car for someone who finds plugging their cell phone in at night to be an onerous burden either. Or who do not have a convenient place to easily plug their car into at night, like a covered garage.
And it is not a car that will save people lots of money or pay for its premium at the current price point and gas at say $4/gallon.
And indeed tested at temperatures about 10-15 degrees below zero the engine needs to help the batteries out if the defroster in on full tilt. Not every day is ideal driving conditions.
I think we all agree on those points. It is not the car for everyone. Some drivers and some conditions may do better than 40 gas free and some much less in the real world.
Of course it doesn’t need be the car for everyone. Just enough of us to sell what they make.
There are some of us who don’t give a shit about a status car (hence my 7 year old Honda Civic that I plan on keeping around until it either dies or my next kid in college makes a good enough case to have it for his use) but who would be willing to pay a modest premium to be able to stick it to the oil producers and help decrease our reliance on the oil producing countries, and/or who believe that climate change is real and want to do our part to reduce greenhouse gasses, and who really hate stopping off at the gas station. Are there enough of us, and is that premium modest enough, to get this segment off the ground, and to a point where they can get production costs to a more favorable point? I think so.
