Tesla are not holding a gun to any manufacturer's head here. What attracts automakers to NACS is the ability to offer their customers Tesla's existing Supercharger network. Fine. Compatibility with that existing network means ensuring that the socket on the vehicle is within reach of cables on existing stalls.
If they only want compatibility with V4 superchargers, they can stick with CCS1 and let their customers connect through the integrated adaptor.
Not only that, but the NACS port is smaller, the overall experience is better, and itβs probably cheaper to make, too. Aptera embraced it as well, in part because their smaller vehicle really benefits from the compact design.
I assure you I'm not worried about it. I'm not expressing a concern. I'm making an observation about what will obviously happen. Any automaker interested in adopting NACS is going to make sure their vehicle works seamlessly with existing superchargers. If that means moving the charge port from left to right (or right to left) then of course they will do it. It's not a big deal.
