I have been machinating on this for a couple days and I think I've decided this is a good thing. CCS Combo 1 and CCS Combo 2 are not interoperable and removing all the AC bits from both doesn't yield a compatible or smaller connector. So there's no real benefit to universal adoption of CCS if there's still two incompatible standards. NACS however is very capable and a much smaller connector than CCS. It has a robust and hardened charging network. And any competing network supporting NCAS instantly expands it's customer base to every Tesla owner, and Teslas dwarf every other EV combined. I have two EVs, one being a Model 3 and the other a Leaf. I initially wanted two EVSEs and had my home spec'd with two 240v outlets in the garage. One of those outlets remains unused because I found a Tesla to J1772 adapter for $100 that works perfectly to charge the Leaf. To add a J1772 charger to my house would cost me at least $500 for a breaker, outlet, and EVSE. I can stow this adapter in my Leaf's glove box and have access to every Tesla destination charger for free in addition to the J1772 network.

CCS 1 and 2 don’t exist anywhere in the same area, right? I know we have 1 in the US and Europe users 2. I assume it’s based on if electricity is 120v or 240v at normal wall outlets, but that’s a total guess. So I’m not sure if CCS having two connectors matters much. I generally agree with the rest of what you said. I’ve considered buying a Tesla Tap to be able to use those destination chargers, and there is a supercharger station far closer to me than the nearest EA station. I understand Ford’s motivations and the CCS experience (I’ve had it). But it seemed like this was largely settled. Tesla missed their chance at being the standard, their connector is better, and I don’t like the confusion this will cause popping up just as non-Tesla EVs are really hitting it big.

  > CCS 1 and 2 don’t exist anywhere in the same area, right? I know we have 1 in the US and Europe users 2. That's correct. Combo 2 is European and the top part is a mennekes connector instead of J1772. My point is that as long as you need 2 standards, one for North America and one for Europe, there's no benefit to the North American standard being CCS1 over NACS. Because of the pervasiveness of NACS at this point, it is easier to just adopt it than to force CCS1 on Tesla. There is already confusion with CHAdeMO, J1772, NACS, and CCS. J1772 can easily charge using AC NACS destination chargers for the cost of a $100 adapter. CHAdeMO will be killed off with the last gen Leaf. It's all the new CCS1 EVs that will be problematic.
