That said, you could probably build this pretty easily - folks have been converting old vehicles into electric cars for, well, decades as well.

And TBH, electric motors aren't that heavy. You still need all the gearing and such with a hand crank.
But they've also been agreeing to buy people's cars back if it's an issue, since selling someone a car with a particular range capacity and then reducing it afterward is obviously problematic.
The Bolt's battery reduction is supposed to be temporary while the final recall fix was worked out. I don't have one so I haven't been following the current news on whether that's been sorted.
In Tesla's case here it sounds worse, because this might be a permanent change where they just said "lol your car is permanently worse now, have fun."
Although in Tesla's case they have been updating the software to restore capacity and charging speeds in many of these cases.
The complete lack of communication is a real problem, though.
Because charging and managing modern EV batteries for optimal range and lifetime is complicated? That's my understanding anyway. If this was easy to do without all the software, why would the manufacturers spend money on it?
They don't sell electric vehicles. Their boffins are working on "EV/AV".
If you're curious, I'd recommend reading Moore's "Crossing the Chasm". I'm entirely for electric cars, but I'm part of what Moore would call the "mainstream market". I don't want a car to be amazing and cutting edge. I want it to work unobtrusively and very reliably. That means that I'm going to be hard to persuade and will want to wait for evidence.
That makes me a terrible initial Tesla customer. For a new tech product, you want early adopters, as they will happily spend money on things that don't work very well. You want the kind of people who will, sight unseen, spend $500 on a flamethrower that isn't a flamethrower. [1]
So given Musk's brand and given the size and wealth of the user base you'd need to launch a new car company, it's pretty much inevitable that Tesla (and now its competitors) were going to mine the technophiles who are happy to pay a premium for sealed-box gee-whizzery.
The good news is that the electric car market will be getting more boring over time. There a lot more people in the more conservative market segments, so although we aren't as profitable per unit as the early adopters, plenty of companies will eventually be addressing our needs.

Those like you (and me sometimes) who do worry about this stuff are not the mainstream market at all.
Note also that Moore's model is specifically about adoption of technology. There are plenty of other dimensions to markets, especially ones where the technology is mature. I think you're talking about people who tend to optimize for initial low price, and are insensitive to other concerns. Which again, people vary on based on product and need. E.g., I have a Pixel 3A because it was good value without junkware and other corner-cutting. But my headphones are the <$20 semi-disposable kind.
Power windows are such a commodity now I wouldn't be surprised if it's cheaper to make a car with power windows rather than cranks.
https://media.gm.com/media/cn/en/gm/news.detail.html/content...
Though they probably do mostly have electric windows; that's more or less a standard feature these days.
If I have to describe it, it would be closer to a 4 wheeled electric-scooter.
The alternative route that I've looking into is to just do the mod myself on an old classic car. There are a few great ev conversion companies like evWest (https://evwest.com/catalog/) and Electric GT (https://electricgt.com/) that offer drop in crates and motors that you can mount. It's not "easy" by any stretch of the imagination but it's a great option to have if you have the time and skills to do so.
Or the cash?
Are there companies that will convert your favorite car to electric, or is that just too much of a liability minefield in the USA?

After seeing the prices for electric motors I'm probably just going to get it running instead.
So yeah, if that's your target, then you can build a much smaller and cheaper pack out of prismatic cells, eg:
https://evsource.com/collections/calb-1/products/calb-100ah
So like, 20 of those is $2800 and would get you 6.4kWh (range of like 30-40km).
What is the reason? Don't automotive manufacturers offer cheap ICE cars? Why would a cheap EV bankrupt them but not cheap ICE cars?
Every inch of the car is well understood. Cheap and reliable parts are available all over the world.
Seriously, me too. I will keep furiously burning fossil fuels until said car is available, and reject all guilt. Any and all emissions produced in the meantime are the fault of the spyware-car industry.
Nice read here that history https://mg.co.uk/behind-the-wheel/electric/the-history-of-el...
And even cheaper if you live in the city: Renault Twizy, Citroën ami, ...
It’s amazingly small, underpowered, and cost efficient (for example, they don’t manufacture separate left and right doors for it, the passenger-side door just opens backwards).
https://www.citroen.com/en/Highlight/131/ami-100t-electric-m...
I really hope that _these_ are the kinds of cars that will get us to mass adoption and not Teslas.
45 kph, range of 70 km, at 6000 euros.
https://europe.autonews.com/automakers/citroen-says-ami-ev-w...
The Renault Zoe is a "normal" car and fit the bill for a more "simple" electric car. They now have the Twingo Electric also which is the size of a usual twingo (roughly like a Citroën C1/Peugeot 107) and cheaper than the Zoe.
It’s because they’re different things.
Just a search for "Renault remote disabled" should be sufficient to get you some headlines.
Cheers!
> According to Norway’s Nettavisen, Tesla didn’t respond to the lawsuit and the 30 owners behind the case were automatically awarded 136,000 kroner (~$16,000 USD) each in compensation unless Tesla appeals to the case, which it has a few weeks to do.
The award amount comes to half a million dollars total. Might be cheaper to just write checks to the 30 people than to tie up corporate lawyers and possibly set a precedent of admission that could trigger other lawsuits.
I think you have misunderstood the potential consequences.
The speculation about 100,000 more owners getting involved is editorialization from this blog, although I suppose some of them will be incentivized to do follow-on suits now that the award value is so high.
Tesla just did the same thing with updates.
(Comments here seem to not understand this context...)
It gets even trickier if it can be shown that the producer was aware that such reductions in range would be quite likely to occur in the near future. When likely transitions to certainty, then it's fraud.
Tesla has actually INCREASED both range and charge speed via software updates, as well.
And there’s no reason to suspect Tesla or Chevy knew for a fact they’d need to do this. People throw “fraud” around way too easily. Usually, when people do that, it makes me think they’re likely perma-skeptics.
Very much like self-driving. The marketing people (Elon) say it's self-driving. The legal people say it's driver assist.
So that's half a million dollars. One wonders if it was incompetence on Tesla's part, or calculated "well, it will cost that in lawyers fees to settle." Dunno. Leaving it unchallenged in court is a terrible look.
Consider you have bought 250mile range EV. Most manufacturers will say that there's nothing wrong if your range degrades by up to 30%, down to 175mile range.
This is quickly changing as we comment.
Just assuming the surprise made it worse.
People are used to ICE cars where you can fill up rather quickly. Fuel pumps put out fuel at different speeds. It's not the same flow rate everywhere and people have no problem with it. Even big tanks on non-commercial vehicles are filled up in minutes.
Refueling an ICE tank is quick and convenient. Electric has not hit that point and comparisons are going to happen. Even if not explicitly.
He also drives from SF to LA about once a month and said it takes 3 stops (so +3 hours?) but the way he put it is "now I arrive much more refreshed because I took breaks on the long drive"
Let’s consider the other end of the spectrum. What about the home of a single mom who needs to get kids off to school, get to work, run errands, and doesn’t have enough time. Also, lives in an apartment. How would this work for her?
There are people who do this with Teslas. It's of course not the most convenient charging arrangement, but it certainly can be workable (and is for a good number of current Tesla owners).
Also, more apartment complexes are adding EV chargers as amenities to attract EV owners. Hopefully charging at an apartment will be less of an issue in the future as these are added.
Additionally, you're going to be charging more often than you'll be filling the tank in a similar sized vehicle.
If you're towing anything then EV is just out the window because they're not capable of towing anything for a long enough distance to be practical.
Really EV's only seem practical if you want to be environmentally friendly imo and even then there are more eco friendly ways to commute. I bike to work often so I feel like I offset my emissions just as much as anyone who's commuting with an EV.
I would agree with his sentiment if I had unlimited vacation time but since I don't, I want to arrive at my destination quickly. I suppose you could set it up to give you the option to stop in interesting places while you charge. Either way you're getting less options when you choose to take an EV on a trip currently, which is why I'll still pass on traveling that way for now.
It also makes me think of a world where your home car is electric, and you rent an ICE for long distance travel. Or where we have real public transit between cities and you rent an electric at your destination. Lots of interesting options that seem feasible on the surface. There will always be a subset that would be better off with ICE though I am sure.
In 20 years what do the old cars on the road look like? Are they all gone? Gone often means in dumps. Where the batteries are toxic to the environment.
If we want to think for the environment should we plan around longevity?
For the landlords it will be a revenue stream. (In leases to the company which runs the chargers)
Will landlords make the money or an outside vendor who does this?
So many questions to ask and so many rabbit holes to go down. Just to look at of this is possible and how it could work
The idea of a gas station likely will just fade away. We have fuel stations because the infrastructure to deliver gasoline to everybody’s home is unrealistically complicated.
But the delivery infrastructure for electricity is largely already there. You just need to install the equivalent of a “pump”.
(Coincidentally there are some guys at my house installing one of those “pumps” today!)
I don't think it'll take too much EV penetration for houses and apartment buildings that are set up for charging to command a premium.
Hey, why not have other solutions.

They would surely complain if Tesla didn't include any "protections" while charging battery (80% capacity by default, slower charge when capacity approaching full, managing battery temperature, etc.)
But can someone explain why some update for charging protections affect mileage? I can understand if they compare capacity per constant time charged and telling us that after x hour charge I could do x miles, but now x-y... but if trying to charge full...? Maybe Tesla just reserves some capacity for longer lifespan of batteries?
At the time I wondered if there was 'reserve' range and turns out there is at least one mile left. But it's clear this isn't the healthiest range to run the battery in.
It's possible they bumped the minimum charge a bit just to urge people to not dip so deeply into the well as often.
It does seem like Tesla realized that the current fast charging + 100% utilization was going to be negative to customer experience quickly (battery degradation) and adapted their charging speed+spare, but they provided no information or guidance to users.
This sounds the same as the Apple situation. In both cases, simply providing appropriate information for users would likely have resolved the whole issue. But they did it quietly and let it be a surprise.
Every li-ion battery needs protection, but there's a world of difference between a performance reduction present before sale and one added after sale.
If you pay for a Porsche Boxster, they can't remotely reduce the performance to that of a Toyota Prius, no matter how good that may be for the longevity, safety and emissions.
Basically there are issues with the BMS that could cause an issue at higher states of charge. They shipped firmware to limit the charge until they could sort out the cause and potentially fix it with software. And it sounds like that part is resolved in many cases.
It looks like the charging issues are different, and he didn't go into those. Anecdotally, I've been hearing a lot of reports of that getting fixed too, though.
But that doesn't exonerate Tesla in any way. Tens of thousands of customers got cars gimped with no official explanation from Tesla. It's been close to two years - that's a significant part of the vehicle's lifetime. Tesla still hasn't admitted any issues and still hasn't compensated the owners - absolute radio silence from them. It's abhorrent
It shouldn't be radical to say that you should control the software that runs on physical devices like cars you own.
Anyone or their business who depended on the old charging speed for mission-critical functions is screwed.
When the batteries in a remote control, clock, or even a car go bad then it’s trivial to change them. So while this problem has existed for as long as battery powered devices have the difference is that no one noticed. Now you can’t change the battery yourself. So it becomes a much bigger burden to understand “oh, the max ability of my battery to charge has degraded.” It’s just a new piece of knowledge for lots of people.
Edit: do note this applies to older cars, it's a bit slower than EVs but 10year old cars will not have the same mileage and power as a new one even with the same specifications.
This is not true, especially the part about "significantly".
The only real mechanism for a loss of performance over time would be if the engine's compression starts to drop as the rings get worn, but this isn't an issue on any modern engine.
Take a car with 10k miles and run it on a dyno. Dyno the same car again at 150k miles and it will probably be within 5%. In fact, performance may even go up as the motor "loosens" up.
This has been my experience.
The amount of dirt a car is exposed to varies by 2-3 orders of magnitude between a farm truck compared to a sports car.
Rarely will you see an old sports car lose more than 20% power. Farm trucks lose 50%+, and the farmers keep running them until they just don't move at all.
*Side note, dirt does sometimes help. As a teen, I had an old ford festiva I shared with my brother. One day we washed the filthy engine bay and after that the thing would not idle. Turns out the dirty grease was plugging a vacuum leak around the pivot on the throttle valve.
Throttling and limiting capacity in exchange for increase durability are inherent to the lithium battery charging process. It seems perfectly reasonable that as field data comes in the OEM would refine the tune.
This is like the EV equivalent of a service bulletin that flashes a new ECU image that actuates some emissions doodad slightly differently to improve longevity or whatever but costs you a fraction of an MPG of a couple horsepower at part throttle.
Yes the messaging to consumers was clearly insufficient but I don't see anything fundamentally wrong here and I'm generally no fan of Tesla.
Apple slowed down your phone because the battery probably couldn't provide enough power to keep it running at its original speed.
But all they need to do is say: do you want us to slow down your device/restrict its battery someway, or run it over spec and it'll be worse in the long term? And let the user pick.
But then they'd be 1000 articles about how batteries are terrible and so are the companies who use them, because terrible journalism
> Sorry you can't keep AC at the temperature you want because doing so will reduce the longevity of this appliance and we can't guarantee it will meet under warranty.
You would find this scenario absolutely unacceptable
Edit in response to the point about Tesla not answering:
That's UK/US legal tradition - but Norway claims (apparently isn't) to be a "rechtstaat"[0]. That means that [the court is legally bound to justice in any case, and that Tesla has constitutional right for justice - best effort must be made even if it didn't respond. This has arisen because many European states of the past abused courts in absence for monetary or political gains, just like this case.
[0] https://en.wikipedia.org/wiki/Rechtsstaat
Edit in response to the point about Tesla having to defend itself:
Sure. But they absolutely shouldn't have automatically lost. The judge must consider all available information about the case and make a fair judgement.
Here it's a case of basic technological principle - all battery packs are throttled, or the battery wouldn't survive a week; that throttling is adaptive to battery health, battery temperature, surrounding conditions, stability of incoming electricity and so on. Tesla doesn't have to supply this information, all that is basic highschool physics (at least in Europe).
// The problem with Apple was about throttling CPU and thus making the device slower in order to make time on battery consistent. This is totally different, and absolutely necessary.
Actions should have consequences.
