I can't wait for 800V Supercharging and maybe over 2,000 mph charge rate!!!!!

Rollout of those will likely take until at least 2030 before they are a significant part of the SC infrastructure

Thanks for the 'stupid' (hahaha) example to try.

Here is my angle and I have done my share of roadtriping in our Tesla.
It can be fine IF you are just traveling from SC/waypoint to SC/waypoint directly
BUT if you want to get off (KEY Point) the "Supercharger Railroad (tm)" [ my term ]
THEN it can be uncomfortable for some parties in the car [ahem: spouse/friend/etc].
In the example below we wanted to go to a couple different hiking/waterfall spots.
It 'mapped' out fine and I gave us some leeway but at the end I was slowing way down
to increase my efficiency. I have several other examples.

BTW, I do watch https://supercharge.info/changes a fair amount and do know the rate of adds.

Great example and let me add a little color commentary, especially since those are my stomping grounds.

So indeed, it worked. I'm assuming that the car was suggesting that you slow down to reach your destination (yes, it does that, if you can't get there, it will tell you).

Today, there's a new Supercharger in Gainesville, (in-between the I-985 and US 23 signs). There's a Supercharger planned in Helen, which it appears that you passed through. There's also a Bucee's on I-75 in Dalton with Superchargers, so you don't have to go as far down I-75.
And then there's CCS chargers in Ellijay, Clayton, and Cornelia, which I think you all went through.

So moral of the story, while there may be a few "stretches" today, they are disappearing quickly.

Where's the best side of the curve?

This is just one graph that I could find. It's close to what reality probably is.
Also, this graph is based on percentage, not time. It makes 80% to 100% look the same as 20-40%.

The number to actually look at, IMHO, is the charging MPH. On a V3, you should start at over 1,000 mph. It won't stay there long and it does require the battery to be below around 10%.
You'll be dropping to 500 mph at around 35%. So you are now at 50% initial charge rate/time.

Watch it the next time you Supercharge at a V3. plot the kW vs speed. And plot the the amount added per minute.

I can't wait for 800V Supercharging and maybe over 2,000 mph charge rate!!!!!

You may also notice here that this graph indicates after 40%, you are at 150 kW, so a V2 charger is just as fast.
Yes, think of it, No need to go to V3 if you aren't below 40%. (assuming that you don't get rate limited by someone plugging in next to you)

MPH varies by the efficiency of *each* car.
Your TM3 is way different than my TMX and will be way different than the TCT. KEY point.
I use kW as my rule of thumb for more consistency/commonality of a measurement.

In general, I go with what the Tesla built-in suggestion is for the next SC waypoint. I'll add some based on my experience (if some), the weather/temp, and the typical speed of traffic on that next road segment. I may add 5% or 10% depending on these factors. I can always slow down or follow a semi-truck at max TACC distance (which my empirical testing has shown to be awesome even at max distance so as not to make them mad).

If I have extra time or my destination has a slow charger ("AirBnB" as 1 example) and have known travels (get food, next days adventures, ...) then I'll add X% but in general I do not like to go below 90 kW.

I’ve appreciated reading your informed and logical posts while lurking these past several years, but this is patently false.

Is it?

Please educate me. I'm always open to being wrong.

And yeah, is that one freeway that's 85 min 65?

So they, going within 10-15 mph of the speed limit, are a road hazard to your speeding by 10-20 mph?

As my current Teslas 'lifetime map' would let you surmise, I have more experience than average in road tripping.
My pro tip is to use the predicted range value (30 mile) vs the built-in nav estimate.
If predicted > nav estimate then you can be pretty darn confident. This works in all weather, roads, etc situations. I've been doing this for years now.

This article I found later mentions some related/tangent things.

Today, there's a new Supercharger

Thx. You factor in what you want your destination timing to be, how long are the side trips (hiking, lunch stops, etc). We had very specific stops for X amount of time. I 100% knew all my options at the time and took into account the factors. Hope that makes sense. The Supercharger Railroad can be limiting when you want to go off the beaten path and enjoy the journey

Total and absolute BS.

The are producing Supercharger pedestals and installing Supercharger sites and high rates. The Pedestals are being made in the NY Gigafactory. They have some of the that are basically drop and go. The land is made ready, the power conduit is installed, and they literally drop off the site prefab on flatbeds.

I can't find the current overall timeline graph, but it is easy to see the rate from the following.
Look at that, 2,000 stations at the end of 2021.
At the beginning of last year, they were adding nearly 5,000 stations per quarter.

Those are Supercharger SITES, not pedestals. They are adding 45,000 pedestals a quarter.

And there's already a number of CCS 800V chargers out there, Porsche has been pushing it for over 6 years.

I could pretty well see all of your hikes and meals from the route. Especially the double-back that you took above the gorge to Clayton, that I was assuming was lunch. I dare say that the CCS in Clayton was right next to where you had lunch. I've used it many times.

Please, before making assumptions take other particular cars and situations into account.

My car does not support CCS without some new hardware upgrade that Tesla is not allowed to be scheduled yet.

I don't recall doubling back anywhere but it would have been a stop/hike and then coming back from it. I don't recall wasting watts as I knew we were close. ... tap tap ... Just looked and Tallulah Gorge /Falls was at that end-point.

Update: Funny thing was shortly (< 1 month) after our visit to Tallulah Falls Visitors Center, Rivian added Level 2 chargers that we could have used with our J1772 adapter.

hahaha, it does look that way. I just haven't found a good excuse to go that way but those states are on my bucket list. I have a friend in Austin but haven't made it there. I've flown into other parts of TX for things. The other places I visit have more scenery that I like. I travel for the journey as well as the destination

Kyle Conner who is very familiar with Cold Weather Driving Range dip and charging expressed his concern..

I find that legit feedback regardless of the numbers.

And that's the way that you do it and it's great.

I know that the Tesla algorithm is very conservative. It doesn't like to bring you in a Supercharger at less than 10-15%. It is currently accounting for things like weather, traffic and road speeds (it didn't use to)
I don't have max follow distance, I'm FSD.

But yes, if I'm on the last stop before my destination, I'll take on a lot more charger, just so that I have some running around room.

To each their own.

I wasn't talking about your car in particular, I was as I assume that you were taking an existing route and showing how it can work for the Cybertruck.

I've got a 2018 Model 3 as well. My Model Y is the one that does the CCS charging.
But then again, all the stops do have CHAdeMO and I do have the CHAdeMO adapter, but rarely use it. The Gainesville Supercharger will make the trip much easier now, maybe a slight detour, but the detour includes a number of possible alternatives for hiking and eating as well.
If you do it again, if you are coming in from Knoxville side (and maybe even Nashville) look at comging off I-75 and going into Ocoee and taking US 64 across. Cuts off interstate, gorgeous drive. and since you seem to be outdoorsy, take a look at the rafting in the Ocoee, the 1996 Olympics course.
