Because batteries are the only part you can criticize, take a look at the sodium batteries made by CATL:

It's a real breakthrough in battery tech. With gasoline you simply can't have this.
(And don't forget that Laserdisk was quite successful for what it tried to do, and that when you buy physical videos today, they're in optical disk format.)
Cars are still sold with J1772/CCS ports, there are still CCS chargers being deployed, there are still J1772 home chargers being sold, almost every level 2 charger is J1772, and my NACS EV came with two dongles.
(FWIW, the new Leaf has a NACS port that's only used for level 3 charging, and separate J1772 port for level 1/2 charging.)
If there was a legal mandate for a changeover, it would be a very different story.

We pretty much need to force NACS: Force all public chargers (level 2 and 3) to be NACS, force all cars sold to be NACS, and make it super-easy for people with older cars to get dongles.
> I think you're underselling how standard it is.
It's about availability:
There's still way more CCS / J1772 than NACS when I use public chargers, or when I look to purchase home chargers. The dealer that I bought my Ioniq 9 had a CCS charger, and the other dealer that I took it to for service had a CCS charger. When I park it near work, it's a J1772. (I wouldn't have bought the Ionic 9 if it was CCS/J1772.)
Searching Google for "What percentage of EVs for sale in the US are NACS" says:
> Transition Period for New Sales: While nearly all major automakers have committed to the NACS standard, many 2025 model year vehicles are still a mix of CCS ports with available NACS adapters, or new models coming with a native NACS port.
> 2026 Model Year: Virtually all new models from every major automaker are expected to come standard with the NACS port
Searching Google for "What percentage of EV chargers in the US are NACS" says:
> As of late 2025, NACS (Tesla's standard, now SAE J3400) dominates in available ports, especially DC fast charging, due to Tesla's massive Supercharger network (over 57% of ports) and rapid adoption by other automakers, with NACS already representing a significant portion of all installed ports, though CCS1 still sees new deployments, creating a dynamic transition where NACS is the majority in Tesla vehicles and rapidly growing across the infrastructure.

What distorts the issue is that so many EVs are Teslas, and that so many chargers are Supercharger. Once you exclude Tesla / Supercharger from the comparison, there's still too much CCS/J1772.
Once you exclude Supercharger
Why would you exclude Superchargers from the comparison of American charging networks? Most V3/V4 Superchargers support charging non-Tesla NACS cars (or non-NACS cars with a dongle), and they're much more reliable than the non-Tesla chargers e.g. EVGo. The reason NACS took off is because the Supercharger network is so good, even for non-Tesla cars.
