Exactly. Start the day with 100% charge from charging overnight, pull into DCFC with 5-10%, charge to ~70% and get back on the road and repeat is generally ideal for EV road trips.
The current reality is that Musk has promised to open the SC network to non Tesla drivers to the extent that they are experimenting in Europe. Now we all know not everything Elon talks about doing comes to pass or not immediately, at any rate, but I was really trying to educate you on some of the aspects of charging a BEV battery that you don't seem to grasp rather than discuss Tesla's plans.
Elon also promised self driving robotaxis in 2019. Until something Elon / Tesla say actually happens, it doesn't matter. Superchargers also have nothing to do with an EA station not working 100%.
For normal use, you shouldn't need to do any math. Rivian predicts your arrival battery % when you set your nav - just keep an eye on that and drive.Wow. Lots of information and MATH!
I will be a new EV owner when I receive my R1S. I am also a VERY challenged math-phobic person.
Question: With all the tech in EVs, don't they do all these calculations for the driver? (Please tell me they do!) If not, does anyone have a spreadsheet with calculations and formulas?
Yes. Tesla offers excellent displays which tell the driver exactly where he is in his energy profile,at a particular point in his trip, what he can expect for the remainder and, most important, how full his battery will be at his destination. The algorithms take into account things like terrain and spped limit changes along the route and are pretty accurate. But you have to understand what they are telling you. My wife is math phobic and none of it means anything to her. I have no idea what Rivian's algorithms may involve but what they present to the driver is much less informative than what Tesla does from what I have seen posted. There is, at least, a display of how many miles you are supposed to have left when at your destination but how accurate that is I don't know. Time should tell. For know I guess I recommend setting the battery display to % and reading it the way you would read the gas gauge in your ICE vehicle.Question: With all the tech in EVs, don't they do all these calculations for the driver?

Rivian's range estimate is a far more useful predictive range rather than Tesla's rated range that is basically useless.
I mean, not really. They have some smarts in the car to have the charger identify the car for billing.
Of course you have no basis for that statement as you have never compared Rivian's estimates to Tesla's but more to the point estimated range at destination is pretty useless without attendent consumption data which is why I do not recommend that people use it and why I am so disappointed in what Rivian has done. Perhaps they will fix with OTA. What you want is estimated SoC at destination and consumption history/projection for the part of the trip you have yet to drive. The energy graphs in the Tesla give this and, once the car realizes how you are driving it (takes a couple of miles), the destination estimate locks in and stays within a percent or 2 for the whole trip). it's amazing.
The vast majority of people do not care about all the data - they want to know if they’ll make it to their destination and with how much charge. Both Rivian and Tesla tell you a predicted arrival %.
That's what the second sentence was referring to.
Well it's a voltage regulated power supply that meets something identical to or very like one of the CHARIN envelopes.
True, alas, and they will be let down but they wouldn't be able to interpret the graphs anyway. I find the "dumbing down" as distressing now as I did when Detroit replace instruments with what we called "idiot lights" years ago. I really hope Tesla won't decide to dumb down the CT.
I too am an EV virgin and have been performing (and continue to!) similar mental gymnastics since placing a deposit on an R1T. Probably the most important thing I have learned from reading hundreds of threads on this forum (thanks everyone!) is that my 'fueling' paradigm needs a major shift for long road trips in an EV. I've heard the same argument from several friends over the past couple of years "you just can't do a 600 mile day in an EV". This thread alone shows how it can be done. If I am heading out for a 500 mile trip in my current truck, I start the day with a full tank of gas (550ish mile range, non-towing). Typically, I stop mid-morning for a coffee/bathroom break, again for lunch, then another coffee/bathroom break mid-afternoon, arriving at the destination and refilling the tank early evening. Looking at ABRP (or other EV planners) it becomes obvious that with an EV I just have to add DCFC charging at my normal stops, for a similar duration, to easily cover the same distance in similar amount of time.
One cannot be let down by something not existing if they didn’t intend to use it anyway
You’ve got it down. Adding DCFC to your existing stops will continuously get easier as more and more DCFC are installed
