Clarity sales averaged around 1000 per month for a while. The change was made to not stock the Clarity in states outside of CA, and now, sales this past month were 400. It's not that Honda NEEDED to move cars to CA to meet demand. If that was the case, the total sales would not have gone down. That is clear. Honda could sell more Claritys if they wanted to. They don't WANT to. I believe that the most likely reason is that they don't make as much money selling them and don't make as much money servicing them.
I am really amazed that there are no longer any PHEVs that are selling in significant numbers (I guess you might call the Prius Prime numbers significant). When you have the Federal rebate of up to $7,500.00, it really brings the price down to reasonable levels. And for most states outside of the Northeast and California, the price of electricity vs. gas is a huge savings. I love the fact that I drive on electricity most of the time and don't have to worry about charging on longer trips. From a consumer side, it makes so much sense, but apparently for the carmakers, they are not attractive to sell.
