Electric cars or hybrids already use much higher voltage than 12 volts.
THat doesn’t matter. You are missing the whole point of my post.
Advances come faster when a greater number of the product is being produced. THere’s more incentive. I’m saying battery tech will improve faster in vehicles that are being produced in greater numbers.
Currently, hybrids are a joke. Nobody cares if they really work or if they pay for themselves. They are subsidized and the costs are hidden one way or another. Otherwise they would never be produced.
