I think that fact they come with free supercharging makes people use it a lot more on the S/X than they perhaps usually would. My guess would be the problem will be a lot less common on Model 3's.
I'm sure that's true. You read people posting about how they only ever supercharge. They seem to think it's like a fossil car where they go to the petrol station now and then, and being free and next to McDonalds they don't see the benefit of charging at home.Some of them seem to think that a 2 hour commute or driving a hundred miles just to do the weekly shop is fine too.
What might cause Model 3 batteries to die will be the fact that they wall want to charge at 300kW. Tesla has always pushed their batteries too hard and then ended up backing off via firmware updates and speed limiting. It's going to be like a party trick, you can do a few "burnouts" to impress idiots but if you do them regularly your car is going to wear out fast.
It's a real problem on the second hand market now. When you buy a Tesla it's hard to know what features it will come with because Tesla might randomly disable them one day, and it's hard to know how knackered the battery is and what kind of charge speeds you will see in six months or a year even if you test it today.
What's interesting though is that there is to my knowledge, no way to decrease your peak rapid charge.
This might seem counter-productive, but if there's not a queue for the charger stations, and I know I'll be X, I don't need to charge in 15 minutes. I'm not saying it should go over say an hour, or even 45 minutes, but in some cases 200-300kW charging would be excessive.

It's done to save Tesla money as much as it is to benefit the customers. Faster turn-around on chargers means they need fewer of them.This might seem counter-productive, but if there's not a queue for the charger stations, and I know I'll be X, I don't need to charge in 15 minutes.

I expect it will only continue to get worse. A new 1000km record was just set in a Porsche Taycan thanks to its higher speed charging. I think it's less stressful for the Taycan battery though because of the higher voltage, which means a lower per-cell current and less heat for a given wattage.

And I appreciate that's the case when busy, but there's a lot of times superchargers aren't particularly busy, can't understand why an App can't adjust for desired charge rate.aestetix1 said:

No that doesn't follow as there would be less in parallel and more in series. Just the ratio of kW to kWh matters.I expect it will only continue to get worse.

That's now how electricity works.P=IV. If you increase V then I decreases for the same P. Note how battery datasheets always look at charge current, not power.
The issue was that when Tesla started it was difficult to handle an 800V battery in a car. Power switching transistors and the like to handle that kind of voltage efficiently were not available or too large/expensive to be practical. Same goes for the charger having to convert AC to 800V DC at 400 amps.
Three years now since taking ownership, first MOT passed with no issues.
Had a chat with the local independent garage who I always go to with my other cars, we decided there was no point in taking the car to them for a 'service' as there is literally nothing they would do beyond what the MOT has done to check the suspension. So going into the 4th year of ownership with me having never 'serviced' the car.
Reliability has been a bit better last 6 months or so, but I still have another 12 months left to run on the factory warranty.
Needless to say the last 6 months has brought lots of changes to everyones lives, for me its the realisation that cars in the grand scheme of things mean very little, and how little we actually need to use ours if we tried. I've done less than 5K miles since end of January, I now walk to school with my daughter and than cycle into work. I'm pretty sure now providing reliability isn't a major factor going forwards our X is probably the last car purchase we would have done for a while now - the fact is can carry bikes with a tow mount has guaranteed its longevity, so I'll keep this post updated yearly but I doubt much will change beyond the yearly MOT, as the main purpose of our X recently has been as a transporter for bikes, a job which its very good at.
I'm still addicted to EVs though, I've done almost as many miles recently on the latest EV purchase than the Tesla!!
I also know what my next EV purchase will be at somepoint in the not so distant future, handling, road feel, a bit of danger thrown in, its the best way to enjoy the British B road and get fit at the same time, unlike Tesla you also tend to get a good discount on the RRP at some point

Good stuff, half tempted by an ebike might try converting one of the old ones I have
Don't bother with converting an old bike, the new ones these days are fantastic and a real revolution in cycling. With the mild e-assistance I managed 18mph average over a reasonable amount of climbing on the hybrid with aero bars. At nearly 20kg loaded up, plus the electrical assistance cutting off at 15mph you still need to work hard if you want some decent speed. But equally you can roll into work at 15mph (quicker than the average speed I use to get in the car on my commute) whilst barely been out of breath. 
It's really addictive stuff, we haven't got many proper hills in Leicester but my in-laws live in Wales. Recently I took my road bike on a blast around unknown single lane Welsh roads with gradients over 13-14%......Climbing up the hills was OK, but descending down those roads in the wet, with 23mm tyres, clinchers was buttock clinching!!!
Going to take the eBIke next time I go, disc brakes, 35mm tyres will be in their element
. Cannot wait to get a road bike with electrical assistance and disc brakes, though am not sure how good that is for my health, as I can barely stay upright on my road bike as it is, going quicker am not sure is a good thing!!

So over 3 years on after taking delivery I was back at Birmingham Tesla service centre yesterday, it was a very difficult place due to COVID compared to the hustle and bustle remeber, and the base spec 3 on show simply doesn't command the same drama as a X and S parked side to side.
The reason I was there was for the MCU2 and AP computer retrofit, its the first time in my life of car ownership a manufacturer has retrofitted their latest/best infotainment system into a 3 year old car!!!
The cost was £2400, not cheap, but alot cheaper than buying a new car. I've had a short period to play with all the features but the touchscreen responsiveness is now instant, and for anyone keeping their S/X with MCU1 for longterm ownership I would 100% recommend it.
The FSD 'preview visualisation' is just crazy to see in real life, even in the dark, loads of glare the car correctly identified a motorbike sandwiched between two cars, and picked up turn arrows on the lanes.
Bring on FSD beta in the UK, I cannot wait to try/see the cutting edge AI software in action.....in our 3 years old+ car. Tesla do alot of things wrong, but they have revolutionised the car industry interms of tech developers and support. More manufacturers need to do the same, and support IT hardware/software upgrades for their cars as time goes on.
Elon has said Tesla will offer new battery tech for all their existing cars in the future, many people doubt him as it means Tesla will end up selling less new cars, but given he has delivered on CPU upgrades, FSD is now making massive progress, I look forwards to getting a new battery pack some time in 2025.
Our X will be with our family for a long time to come yet.

No. I refuse to take part in Tesla's beta testing. Use your own private road if you want to do that.
Don't worry nearly all of European legislators have your mindset. This is what 'advanced summon' can now do in the US, the first 10 seconds is crazy, even I was confused at what was going on. In Europe we get go forwards and back whilst staying within arms length....https://youtu.be/fPky1ctTAik
So whilst the US forges ahead with this new tech, and its not just Tesla Uber/Waymo, Europe is fast been left behind. If you are a super geek, clever enough to actually work on this kind of tech where are you going to be sending your CV?
