On Tech: Electric cars, cool. But when?

Electric cars, cool. But when?

Nicholas Law

It's great to imagine a future of efficient, pleasant transportation that does less damage to our planet. But let's get real: Revolutions don't come easy.

Today I'll tackle a couple of questions from readers about my interview this week with my colleague Neal Boudette about electric cars: When will the cars have longer battery life and more charging options? And will old electric car batteries be a hazard?

Let me first stress: Most environmental experts say that shifting to electric vehicles, particularly combined with generating more energy from renewable sources, can make a big difference in slowing the effects of global warming.

Where's the infrastructure? Readers including Stacy Elwart from Venice, Fla., and Tom Rowe from Stevens Point, Wis., had similar concerns: How can electric cars reach a tipping point if charging isn't widely accessible and convenient, and when ranges still fall far short of what gasoline cars get per tank?

Brad Plumer, a reporter from The New York Times's Climate team, explains what is happening to tackle the challenges of charging and battery life:

Many newer electric models, like the Chevrolet Bolt and Tesla Model 3, can go well over 200 miles before needing a recharge. That can be quite practical for most daily trips, but not for longer trips or people who don't have places to plug in their cars at home.

So some companies, like EVGo, are now building hundreds of fast chargers, which can typically add about 100 miles of range in 20 to 30 minutes. That's slower than refueling at a gas station, but it can make a road trip more doable. There's hope that further battery advances could speed up charging times significantly. Automakers are constantly trying to improve the range.

Many local governments and electric utilities are also trying to build networks of public chargers, but it's a huge undertaking and many cities are way behind. It's the chicken-or-egg dilemma: Companies are reluctant to invest in chargers until there's a critical mass of electric vehicles. But some people are wary of buying an electric vehicle without better charging options.

It also can take time for utilities to upgrade their grids to handle more electricity demand.

In the short term, these challenges probably won't stop electric cars from becoming more popular as battery prices plummet and more governments push away from conventional vehicles. By 2030, electric vehicles are expected to be 20 percent of new sales in the United States, according to analysts at BloombergNEF.

But, the analysts warned, sales could eventually hit a bottleneck without a major build-out of charging infrastructure. Expect charging to get a lot more attention in the years ahead.

What happens when electric car batteries have outlived their use? This one came from Steven Permut in Tucson, Ariz.

The lithium-ion batteries that power smartphones and other gadgets can be an environmental and safety hazard. (Fires at recycling centers are a problem.) Electric cars have really big lithium-ion batteries. It sounds like a potential disaster, if and when large numbers of electric vehicles are eventually put out to pasture.

But Adam Minter, a columnist at Bloomberg Opinion (where we were colleagues) and the author of two books on reuse and recycling, told me that electric vehicle batteries can have a useful second life.

Old stuff, Minter told me, is "a source of an incredible level of innovation — and you're beginning to see that with electric car batteries."

He pointed out eBay listings in which used Tesla car batteries go for hundreds or thousands of dollars. Vehicle batteries with some life left are refurbished to convert conventional cars to electric in some countries or are turned into generators and energy storage, Minter said. And in China, the world's largest car market, there have been major investments in recycling infrastructure for vehicle batteries. (Although Greenpeace recently said that China wasn't doing nearly enough.)

Minter still has concerns about the potential environmental harm from manufacturing electric vehicles and their batteries. But, he added, "I'm confident there are good uses" for spent batteries.

Neal also told me about a few younger companies pursuing what he thinks are promising approaches to vehicles of the future — though they're far from guaranteed to succeed. Here is Neal's take on three of them:

Rivian is a really interesting company to watch. It's planning to manufacture its own software-powered electric cars like Tesla — it bought an auto plant in Illinois that had closed. But Rivian is more pragmatic and will follow a lot of established car manufacturing steps that Tesla ignored and then regretted doing so.

Another company, Lucid, thinks it has found a way to squeeze every last bit of energy out of batteries, and it plans to release a car that it says will travel up to 500 miles on a single charge. Lucid's cars will probably be very expensive— $100,000 or more — but it's an interesting concept.

There's another company called Arrival that is working on electric delivery vans and buses with a unique approach: Its vehicles will use giant plastic panels instead of sheet metal. Robots and workers will effectively assemble one vehicle at a time with simplified processes and parts.

Arrival is also talking about manufacturing vehicles in "micro factories" that are close to the eventual vehicle buyers. I don't know if it will work, but it's a totally radical way of looking at things. This is not just making another vehicle that doesn't use gasoline.

Before we go …

  • A tax law that's about way more: Maryland is on the verge of approving a first-in-the-nation tax on Google and Facebook's digital advertising, my colleague David McCabe reported, and it's likely to start a legal fight over how far strapped American communities can go in trying to tax Big Tech.
  • A place for effective conversations, and horrible ones: Bloomberg News wrote about Black medical professionals who found that the audio chat room app Clubhouse was an effective place to hear out and dispel misinformation about the coronavirus, but the efforts also exposed them to harassment or bullying.
  • An unsolicited plug for your local library: Public librarians and readers (including me) love the Libby app for borrowing and reading e-books. But Protocol reported that because e-books are regulated differently than physical books, they are costing libraries a fortune.

On Tech: Twitter vs. India

Plus, do we really hate fighting on Facebook?

Twitter vs. India

Karan Singh

A remarkable face-off is unfolding between an American internet company and the world's largest democracy over the appropriate bounds of free speech.

The backdrop is ongoing protests of farmers in India opposing new agriculture laws. The Indian government, citing its laws against subversion or threats to public order, demanded that Twitter delete or hide more than 1,100 accounts that it says have encouraged violence or spread misinformation.

Twitter has complied with some of India's orders. But Twitter has refused to remove accounts of journalists, activists and others that the company says are appropriately exercising their right to criticize the government.

The government of Prime Minister Narendra Modi is saying Twitter is breaking the law. Twitter is saying that India is breaking its own laws. And democracy activists say that tech companies like Twitter shouldn't play along when governments pass laws that effectively shut down free speech.

There are regularly disputes between internet companies and governments — both democratic and not — over whether posts break a country's laws. What's unusual here is how public and high profile the disagreement is, and that India has threatened to imprison Twitter employees.

I spoke with David Kaye, a law professor at the University of California at Irvine and former U.N. special rapporteur on free expression, about Twitter's decisions in India, how they may reverberate and the consequences of a few tech companies setting the rules of global discourse.

Shira: Do you think Twitter is making the right call?

Kaye: Yes. Twitter is essentially saying that it won't comply with orders it considers inconsistent with Indian law and that violate people's human right to free expression.

Under the Modi government, India hasn't acted democratically on the rights of people to speak out against their government. I'm not sure why Twitter chose this moment to take a stand and not two or three years ago, when the company took action against people posting about Kashmir after pressure from the government.

In my role at the United Nations back then, I asked Twitter to explain what happened. The company didn't answer. In a way, this week was Twitter's response.

But Twitter is defying a democratically elected government.

People shouldn't be under the impression that these companies see themselves as above the law. An important distinction in India is that the order came from a government ministry — not a court. Twitter is saying that India's demands to block accounts or remove posts didn't come through the regular rule of law.

What other questions does the standoff raise for you?

I have the same question that people asked after Trump was barred from Facebook and Twitter: What about all the other countries? Will Twitter also be more forceful in standing up to governments in Turkey, Egypt or Saudi Arabia? And how far is Twitter willing to go? Would it risk being blocked in India?

(Twitter does not automatically comply when a government — including the United States — requests that the company pull down content or hand over users' data. Here are Twitter's disclosures on how often it responds to such requests by the authorities in Saudi Arabia, Turkey, Egypt, India and the United States.)

How should we feel that a few internet companies have the power to shape citizens' engagement with their governments and set the bounds of appropriate expression?

It's a problem. These companies have massive and largely unaccountable power. The fundamental question is: Who decides what is legitimate speech on these platforms?

Both the internet companies and governments deserve blame. The companies haven't provided transparency into their operations, their rules and their enforcement. Instead we have perpetual cycles of what look like seat-of-the-pants decisions in response to public pressure. And governments have largely not done the hard work to create smart regulation.

What does smart regulation look like?

The challenge for democratic governments is to enhance the transparency of social media and put it under a regulatory framework — but not impose content rules that are abused and interfere with the free speech rights of users or the rights of companies to create an environment that they want for users. That's the persistent tension.

The European Union's proposed Digital Services Act is quite sophisticated legislation on this. The U.S. is still screwing this up.

(Also read Tom Friedman, the New York Times Opinion columnist, who writes that he's rooting for Europe's strategy for regulating the internet.)

Do we really hate fighting on Facebook?

The reason, Mark Zuckerberg explained recently, is that people told Facebook that they "don't want politics and fighting to take over their experience." But, uhhh, have they seen Facebook?

As my colleague Kevin Roose has reported relentlessly — and as an account he created tweets daily — the Facebook posts with links that tend to get the most reactions, shares and comments are overtly political fests of rage. So what is Facebook doing? Kevin and I chatted about this:

Shira: Haven't your analyses shown that people do want politics and fury in their news feeds?

Kevin: People contain multitudes, and their stated preferences often don't match their revealed preferences. If a nutritionist surveyed me about my ideal diet, I'd list healthy foods. But if you put a Big Mac in front of me, I'm going to eat it. I find it believable that Facebook users say they don't want politics and fury, but when their friend posts a great Bernie Sanders meme

I also suspect that a relatively small number of people are responsible for a huge amount of interactions on Facebook — and that those super sharers are really into politics. Facebook says that only 6 percent of what users in the United States see is political content, so most of Facebook really might be Instant Pot recipes and baby photos.

Is Facebook's silent majority the people who don't want all the politics?

Possibly! Or people just aren't honest about (or don't know) what they really want. I guess we'll find out from this Facebook test.

Should Facebook give us more of what we actually click on, or what we say we want to click on?

Facebook, like basically all social media apps, is designed to give us more of what we like. It's very lucrative, but this hasn't gone so well for democracy.

So what if a social network were designed to feed our aspirational selves, rather than our lizard-brain impulses? Would we like it more? Or would we miss the drama and the fighting?

Before we go …

  • America's unofficial unemployment hotline: During the pandemic, more Americans have turned to a Reddit message board for advice on navigating the confusing unemployment insurance systems, my colleague Ella Koeze writes. It's also a place to commiserate with others going through the same difficult circumstances.
  • Falling into the algorithm void: Companies that make specialized clothing for people with disabilities say that Facebook's automated systems routinely reject advertisements and listings for their products. The problem, my colleague Vanessa Friedman writes, is that computers are bad at nuance and Facebook's systems often flag adaptive clothing as medical equipment promotions or "adult content," which is against the company's rules.
  • The digital divide, at church: Wired writes about the churches that have thrived as worship largely moved online during the pandemic — and the struggles of others that didn't have the resources to go virtual.
