You seemed to be making the argument that without solar owning an EV may not make economic sense for the EV owner. I don't think that's related to the outcomes of the transition to an EV mandate for new sales, which is what the respondent was asking about. Sure, it's nice to have your own solar panels, but it's not a requirement for EV ownership, and I was pointing out that your assertion, whether true or false, was unnecessary for the EV transition to be a "good idea" in the parent poster's words. That said, regardless of how you power your vehicle, even in some of the most expensive power markets, overnight charging is cheaper than gas, both economically and environmentally.
