L2? L2.99? China and the U.S. are both failing to regulate self-driving cars

Marketing language often refers to the future, not the present — and drivers in both countries are getting confused, and sometimes hurt.

The tech worlds of the United States and China are usually operating on different timelines: Either the Americans lead in one field or the Chinese lead in another. But this past week, the two countries have found themselves in sync on one issue: the failure of proclaimed self-driving cars to … actually drive themselves safely.

Auto industry disruptors who have made a name for their pioneering autopilot systems are being questioned in both countries about whether these systems are causing severe travel accidents. In the United States, the National Highway Traffic Safety Administration just opened an investigation into Tesla's Autopilot feature following 11 traffic accidents that happened in a specific night driving scenario. In China, NIO, one of the leading Chinese autonomous vehicle makers, got grilled in the media after a fatal car crash that happened when NIO's autopilot system was at work.

In both countries, the controversies and media attention go back to the discrepancy between dream and reality: While these new auto brands are known for taking the world one step closer to self-driving cars, the actual cars being sold are still far from fully autonomous. Beijing and Washington are increasingly asking whether these car makers are promising too much and misleading drivers into over-dependence on their vehicles.

For now, neither Chinese or American auto regulators have found the answer. It's the drivers of Tesla, NIO and many more smart car brands who are shouldering the cost of this still-futuristic dream.


Pick a number between (L)2 and (L)3

On Aug. 12, 31-year-old entrepreneur and investor Lin Wenqin died in a highway traffic accident in southeast China. Photos of the scene show that the NIO ES8 that Lin was driving, a high-end SUV model comparable to Tesla's Model X, crashed into a heavy-duty vehicle parked on the highway. According to an obituary released by Lin's friends and family two days later, Lin's vehicle was on NIO's "Navigate on Pilot self driving mode" when the accident happened.

The possibility that a self-driving system is to blame for the accident immediately caught social media's attention. To date, the police haven't updated the public on their investigation, and the company NIO said in an announcement that it won't release any information before the police inquiry is finished. But when answering a question from the Chinese publication Beijing News, NIO emphasized that "NOP is still an assisted driving feature. It should not be seen as a self-driving feature." NIO didn't respond to Protocol's request for comment.

The question is whether the victim, and the drivers of NIO and other autonomous vehicles, know the difference.

The United States and China have similar standards to define how "autonomous" a vehicle is. Cars are grouped into six categories, from L0, where the driver controls everything, to L5, where the car performs all tasks. Today, the Japanese brand Honda boasts the only mass-produced model that has reached L3, the Honda Legend, a critical milestone that frees the driver from watching the road.

But the clarity on paper doesn't translate well into reality, especially when it's not always in the car manufacturer's interest to admit how limited their self-driving technology is.

The many Chinese car manufacturers that have yet to reach L3 have focused on how to make their assisted driving technology sound more appealing than their competitors'. As a result, they have marketed their cars using terms like "L2 Plus" (BYD), "L2.5" (Jetour), "L2.75" (XPeng) and even "L2.99" (Chery).

The numbering system is confusing, but it gets even worse when companies are coming up with acronyms. Between NIO's NOP (Navigate on Pilot) and NAD (NIO Autonomous Driving), Tesla's NAP (Navigate on Autopilot), and XPeng's NGP (Navigation Guided Pilot), it's become hard to tell which technology is more advanced.

In the United States, Tesla has gotten into plenty of trouble for calling its Autopilot system "Full Self-Driving." In China, other car brands have deployed the same tactics to, purposefully or not, blur the boundaries between assisted driving and self-driving. The most egregious example, according to Xing Lei, an auto industry analyst and former chief editor at the Beijing-based China Auto Review, is when the Shanghai-based brand Weltmeister publicly advertised in April that it had "the first mass-produced self-driving car in the country," equating to L4. But later it was revealed that technology was only available when the car was parking.


Blurred lines

Perhaps the bigger problem is the gulf between assisted driving — what an L1 or L2 vehicle actually offers — and "self-driving" or "autonomous driving."

After the recent highway accident, Li Xiang, founder and CEO of Chinese car brand Li Auto, called on the industry to refrain from using the word "自动" (which means "self" or "autonomous") in its marketing before reaching the L4 stage.

On paper, NIO seems to have done a decent job explaining its technology. According to Chinese publication LatePost, in NIO's 100,000-character-long driver's manual for its ES8 model, it only says "self-driving" once, and that's to warn that autopilot does not equate to self-driving. On its website, the word also never appeared when describing its currently available models.

"I've talked to three or four salespersons of Tesla China and two salespersons of NIO," a Shenzhen-based Tesla owner who wishes to stay anonymous told Protocol. "When I asked them if they have self-driving cars, they all seemed well-trained and told me it is assisted driving, not self-driving."

But some buyers aren't content with NIO's efforts to teach the difference. In a discussion forum on NIO's app, one buyer nicknamed "the unfillable stomach" wrote: "I can tell you loud and clear that it's impossible" for everyone to understand NIO's autopilot system correctly. "At least when I bought the car, I was told by everybody that Navigate on Pilot gives you self-driving."

Drivers clearly differ in their views. Soon after the accident, 500 NIO owners signed an open letter in support of the company, pledging the company has done a good job teaching them the differences between assisted driving and autonomous driving. But then came the backlash, with other NIO drivers starting a hashtag "Reject the Open Letter" on NIO's app.

Customers often want to think that their cars are more powerful than they actually are. "After autonomous vehicle companies exaggerate their capabilities, some consumers, especially those who are young and chasing after new technologies, may try to show off or play with the system," Xing told Protocol, "and that's very dangerous."


What, me regulate?

Evidently, neither Chinese nor American regulators have a handle on this problem. On the same day of the fatal accident, the Chinese Ministry of Industry and Informational Technology published a new regulation that asked autonomous car makers to ensure there's a safety mechanism to detect whether the driver's hands are still on the wheel. But the U.S. and China are both on a blank page when it comes to determining whether auto companies are exaggerating their technologies, and to what extent that should be forbidden.

Meanwhile, car makers continue to depict a great driverless future, even if that's not yet offered by a particular product they currently sell. While NIO has been careful about not calling its current pilot system "self-driving," it freely sprinkles the word in when describing its latest technology, NAD, a more sophisticated system that will be released on NIO cars in 2022. Once released, NAD will bring about "a safer and more relaxing autonomous driving experience from point A to point B," the website says.

As always, the devil — or in this case, the reality — hides in the fine print. At the bottom of the NAD page, a line reads, in light grey color and smaller text: "NAD in the description is designed for driver assistance purposes only and cannot fully replace driver's control or handle all possible traffic, weather and road conditions."

Why Twitch’s 'hate raid' lawsuit isn’t just about Twitch

When is it OK for tech companies to unmask their anonymous users? And when should a violation of terms of service get someone sued?

The case Twitch is bringing against two hate raiders is hardly black and white.

It isn't hard to figure out who the bad guys are in Twitch's latest lawsuit against two of its users. On one side are two anonymous "hate raiders" who have been allegedly bombarding the gaming platform with abhorrent attacks on Black and LGBTQ+ users, using armies of bots to do it. On the other side is Twitch, a company that, for all the lumps it's taken for ignoring harassment on its platform, is finally standing up to protect its users against persistent violators whom it's been unable to stop any other way.

But the case Twitch is bringing against these hate raiders is hardly black and white. For starters, the plaintiff here isn't an aggrieved user suing another user for defamation on the platform. The plaintiff is the platform itself. Complicating matters more is the fact that, according to a spokesperson, at least part of Twitch's goal in the case is to "shed light on the identity of the individuals behind these attacks," raising complicated questions about when tech companies should be able to use the courts to unmask their own anonymous users and, just as critically, when they should be able to actually sue them for violating their speech policies.

While it's easy to get lost in the operational and technical side of a transaction, it's important to remember the third component of a payment. That is, the human behind the screen.

Over the last two years, many retailers have seen the benefit of investing in new, flexible payments. Ones that reflect the changing lifestyles of younger spenders, who are increasingly holding onto their cash — despite reports to the contrary. This means it's more important than ever for merchants to take note of the latest payment innovations so they can tap into the savings of the COVID-19 generation.

When COVID rocked the insurance market, this startup saw opportunity

Ethos has outraised and outmarketed the competition in selling life insurance directly online — but there's still an $887 billion industry to transform.

Life insurance has been slow to change.

Peter Colis cited a striking statistic that he said led him to launch a life insurance startup: One in twenty children will lose a parent before they turn 15.

"No one ever thinks that will happen to them, but that's the statistics," the co-CEO and co-founder of Ethos told Protocol. "If it's a breadwinning parent, the majority of those families will go bankrupt immediately, within three months. Life insurance elegantly solves this problem."

Remote work is here to stay. Here are the cybersecurity risks.

Phishing and ransomware are on the rise. Is your remote workforce prepared?

Before your company institutes work-from-home-forever plans, you need to ensure that your workforce is prepared to face the cybersecurity implications of long-term remote work.

The delta variant continues to dash or delay return-to-work plans, but before your company institutes work-from-home-forever plans, you need to ensure that your workforce is prepared to face the cybersecurity implications of long-term remote work.

So far in 2021, CrowdStrike has already observed over 1,400 "big game hunting" ransomware incidents and $180 million in ransom demands averaging over $5 million each. That's due in part to the "expanded attack surface that work-from-home creates," according to CTO Michael Sentonas.
