you didn't respond to the more important point that is that driver did 8+ typical years of driving in a tesla and his battery life dropped a whopping 3%.
and model 's have been out there for what, 7 8 years now and i haven't heard of disastrous degradation. maybe you need more data, but obviously a lot of people are convinced at this point.

I would disagree, since the Tesla folks invade every single car thread on this and several other (non-car-related) forums I frequent.
"What's the best reliable daily driver under $5k?" "You should really get a Model 3"
Anti-Tesla folks generally only threadcrap in response to Tesla posts.

you're apparently the only one speculating on here. tesla model s has been out over 7 years. no battery issues reported that i've seen. i know people who have had them several years too... no noticeable degradation at all.

i just moved your post here as it was in an unrelated thread (presumably accidentally), and quoted here so others see it. thanks.

Theory
1) Even when they are sitting around doing nothing, all batteries degrade due to side chemical reactions.
2) The faster the supercharging and the greater the frequency of supercharging, the greater the battery degradation.
3) The more fully a battery is fully discharged to 0%, and the more fully it is recharged to 100% - for maximum range - the greater the battery degradation.
In other words, if range is minimized, then battery longevity will be maximized.
4) The smaller the battery pack per vehicle [nee Model 3], the harder the smaller battery pack has to work to keep up with a larger battery pack [nee Model S], then the greater the smaller battery pack's degradation.
Practical
Be patient, wait and see as independent 3rd party data is released.
Presently, it is too early to call.
Never say that Model S has been out 7 years, because the bulk of Model S data [statistically significant sample numbers] is only 2 years old!
The Model S's that have been around for 7 years are too small in sample number, and therefore statistically insignificant.
Focus not on the years, but on adequate sample numbers.
Wait till the smaller Model 3's data with their smaller battery packs are released; smaller batteries must work harder - so you know what to expect.
I haven't seen any Model 3 data released, or you know of some you can post???

Gasoline range DOES reduce as cars age. Fuel economy degrades, thus so does range.
Batteries have two issues, one is their range degrades, and two is the speed at which they charge degrades. MANY examples online and on Youtube of Tesla owners with 200k+ miles and discussing their range loss and recharge speed loss.

I haven't seen those Teslas lose anywhere near 30%. Most lose 5-10% at most. Sure sample size is small but really, if you have the entire sample size saying the same thing, its usually a good predictor of the larger sample size to come. No way i'm keeping this car past 8 years though. By that time, EVs will have double the range and do 0-60 in 2 seconds

Wow... the spin machine is at full steam for this car. It's like Elon Musk's life depend on its success or he will wake-up all bloodied and tied-up in the trunk of a Cadillac driven by upstanding Chinese men on the way to a slaughterhouse.

How do you know if battery degradation follows an inverse curve, or a negative sigmoidal curve with a reverse bend?
In fact, most batteries degrade with a negative sigmoidal curve with a reverse bend - that signifies a rapid fall after a certain point.
Maybe Tesla has come with a miracle lithium ion that has a simple inverse curve battery degradation similar to motor vehicle depreciation?
And what about waiting a few years for initial Model 3 data to be released, because its smaller battery pack must work much harder than Model S?

good idea, why don't you wait for a few years until the data you want is available so your graphing ability have data to use. until then, give it a rest.

In theory we know batteries must degrade.
The practical will tell us how soon and by how much...
