Response to Knightshade;
If that were true then Teslas wouldn't have way better resale value than even ICE cars in the same class.... (Leafs, with crap batteries, sure don't)
What's self evident is the current lifespan of Tesla batteries is already "good enough" for resale buyers to be 110% fine with it- otherwise they wouldn't be paying significantly more for a used Tesla than literally any comparable vehicle EV or ICE.
Ah but see, this is moving the goalposts a bit. Between EVs (not vs. ICE cars), a million mile battery is an objectively good thing. There's no arguing against this. Why cherry pick?
Not any more than a "1000 mile range" battery helps range anxiety in a country where the average person drives under 30 miles in a day.
It's great for marketing and mental blocks, but not of much practical value given cars are rarely driven even 100k miles before being resold the first time.
You're simply arguing degree. I'm simply arguing an objectively good thing. There's nothing 'bad' about a million mile battery. Why work so hard to exclude this obvious potential benefit?
Also, don't forget that range is not the only metric here with respect to miles-driven. *How* you drive matters. I like to drive assertively or at a brisk pace but within reason, and California freeways in free-flowing conditions are quite fast too. A 30 mile commute is one way for me, and I think your 'under 30 miles a day' figure is wildly off the mark but for pandemic exceptions. For all of my working life, my commute has averaged about 30 miles one way. This is even more true for homeowners who end up having to commute since they don't have the option of renting an apartment close to a brick-and-mortar workplace.
That said, my 60 mile commute is never just 60 miles of range loss due to free-flowing (fast) traffic in SoCal, my driving habits (for fun but also to make effective overtakes), etc. I sold my LEAF because even 150 miles of range wasn't practical for more than a couple days of driving. There are other factors which drain range too such as hills, weather (more A/C or heating), etc. So, if a long life battery means more range retained over the life of the battery, that's an objectively good thing, no?
Which currently don't exist, so probably not a huge bump to sales right now.
But it's in Elon's stated goals, and it certainly looks good for investors to see 'million mile batteries'. Someone's going to be the first to market, and solid battery tech will be an important feature for the business model (and attracting investors).
I'm not really sure the typical uber driver amortizes his vehicle over 30 years..... (in fact isn't there a rule for some classes of rideshare that you can't use a car if it's more than a certain # of years old? so NO help there at all to those folks).
True, but it *does* affect what drivers buy. Again, there are a constellation of metrics in play. Having a 'million mile battery' is objectively better than not, and objectively better than the competition that doesn't have it.
For heavy duty fleet users (the one example cited being Tesloop- which owns SEVEN WHOLE CARS!) those guys are mostly buying unlimited-mileage-warranty S/X models and burning through several stock batteries at $0.00 cost to themselves... so I guess for the literal number of cars you can count on your fingers a million mile battery helps Teslas warranty costs by that amount
)
Sure, but just like the TSLA stock discussed at-length in this very thread, you have to consider both human behavior and the future of EV manufacturing, efficiency, appeal to the mass market, competition against other cars (and EVs) as it affects sales, etc. A million mile battery is a welcome addition to all of the other benefits we get from Tesla. Certainly, it'll be a huge contrast from cars notorious for their lack of battery life and tiny ranges.
All told, I'm in favor of any battery advancement for EVs as a whole, and especially so as a TSLA stockholder and Model 3 owner.
