I think that you may have missed some of this thread. Tesla chargers are available to Rivians today. But Rivian chargers aren't open to anything except for Rivians yet...
I guess I wasn't clear. My table is supposed to illustrate what
might happen
in the near future. (Unfortunately, I can no longer edit the table.)
Also, as I said, I am not sure what all the various DC fast chargers are doing right now, as I don't use them much, and I haven't visited areas in most of the US (outside of California) since owning an electric car.
Actually, the exercise of preparing that table was beneficial (to me), as it made clear that things (vis-à-vis charging) would probably not be too bad in the coming years. As I said, the use of a few simple adapters should take care of most compatibility issues until the time when all charging stations and cars are using the NACS equipment. And you are correct: drivers of certain (older) cars can continue to use CHAdeMO adapters (if they have access to that 50 kW-max DC charge equipment). And you are also correct, that CCS1 as a charging technology will gradually fall by the wayside. However, I think it may take a little longer than you predict. We'll see,
Naturally, in my post I was
not figuring in apparently perpetual problems like broken chargers, copper wire theft, vandalism, crowding (at popular charging sites), the perennial lack of adequate numbers of charge facilities in less populated or outlying areas of the Country, and so forth. Even the superior Supercharger Network is subject to some of those things, correct?
I hope for a time when most or even all drivers are behind the wheels of BEVs (or some other safe, non-petroleum-fueled vehicles). But we've already seen the legitimate and not-so-legitimate push-back by the makers of ICE, PHEV, and FCEV vehicles specifically against BEVs. (Misinformation and behind-the-scenes lobbying by Toyota springs to mind.) I suspect that
some (not all) recent reports and (almost gleeful) analyses of the downturn in the sales of BEVs were at least in part exaggerated, disingenuous, or even falsified in spin pushed to the media by those in the employ of BEVs' competitors. This is to be expected, unfortunately. There will be more coming as electric vehicles continue to make inroads. (For my part, I blame not only the perpetrators of "fake news," but also the ever-money-and readers/viewers-hungry News Media for not adequately vetting stories, of all kinds, adequately.)
As far as to how long the CCS1 will stay around, well, you've already forgotten one of the more prevalent until just recently plugs, the CHAdeMO which is used by Nissan. There are a LOT of Leafs still on the roads. But many people have forgotten or don't even know what was recently one of the most prevalent DCFC solutions on the market.
For my part, I have not forgotten CHAdeMO; I just chose to leave it off of the table since my focus, and the focus of the OP, was on Rivian and Tesla today (and in the future). I still have my (big 'ol) Tesla CHAdeMO adapter. I never use it. (Why not sell it? Because it cost me only $75 [that is a whole other story] and there is [or was] a CHAdeMO-outfitted 3
rd-party charger near me, So I figure, keep it in the sub-trunk, just in case, you know?)
I am curious. Other than for Nissans, did all that
many BEV drivers
actually use CHAdeMO adapters much in North America? Of course some drivers used them a lot. But was popularity actually widespread? I think not. CHAdeMO technology was and may still be popular in Japan for all I know. But I have not seen actual data for North America.
I am aware that in NA outlying areas and in locations in Hawaii, for example, CHAdeMO was (and perhaps remains?) popular, because it was all that was available (in places with no or few Superchargers). However, as you point out, once the Supercharger network grew and more powerful (and hence quicker) CCS1 chargers came on the scene (thanks for screwing up royally, VW, and therefore giving us the "Electrify America" Network), CHAdeMO quickly disappeared from the proverbial radar screen (at least in moderately well-populated areas).
Sure, there will be CCS1 stations out there, but as the CHAdeMO, they will start to fall out of use quickly. In a very short time, maybe 1-2 years, there will be more non-Tesla NACS vehicles on the road than CCS1 vehicles.
Why do I keep saying CCS1? Mainly to enforce that North America is about the only location that uses it. Europe is on CCS2, a different plug.
Yes, I am also very aware that North America is the only area where CCS1 is used. (It's CCS2 in Europe and Oceania.) And the NACS (originally the Tesla proprietary charging standard) ports and plugs are/were pretty much only used in NA, Japan, and South Korea.
For new readers, here are some threads I've started over the years (from oldest to newest) relating to charging equipment:
