If Elon wanted to create a "standard," he should have opened this up back in 2012. It's not as if it would have hurt Tesla's competitive advantage over other EVs available in those olden days.
It does make you think that this could be the the gateway to using Tesla superchargers by other manufactures, Aptera may be the first.
I don’t see Tesla making a CCS-socket to Tesla socket adapter. Years ago the J1772 committee screwed up by not adding a strong DC specification. The FRANKENSTEIN plug shouts kludge. Bob Wilson
Are you sorry for Tesla who originally made their charging-system designs proprietary but finally realized they made a mistake and now want them to be an industry standard?
Since the growth of Superchargers exceeds my expected battery degradation, no regrets. In fact, I’m not fond of non-Tesla EVs trying to use Superchargers. For example I saw a Leaf owner leave in disgust when they could not Supercharge. Apparently there is a hack that claims to work but not in their case that day. Supercharger envy is a thing. But having a CCS equipped BMW i3, I am ambivalent about getting the Tesla released adapter. Slow, expensive, and unreliable has little appeal. BTW, the local Supercharger rate is $0.33/kWh versus $0.12 home rate. I only use the local Supercharger when Bob Wilson
