In certain sunny climes, self-driving cars are multiplying. Dressed in signature spinning sensors, the vehicles putter along roads in California, Arizona and Nevada, hoovering up data that will one day make them smart enough to run without humans.
Besides perennial sunshine, those places share other common traits: wide, well-manicured roads, functional traffic enforcement, and agreeable local governments. That’s how Chandler, Arizona — a Phoenix suburb on nobody’s radar as of a few weeks ago — became the first US town to host autonomous cars on public streets without human safety drivers. Courtesy of Waymo, they’re expected to start carrying passengers within the next few months.
If you ask many Silicon Valley companies, the future of driverless cars is just a couple of years away. But halfway across the world, the outlook is a lot more skeptical.

“We don’t have the luxury of California roads,” says Olga Uskova of Cognitive Technologies, a Russian software maker that specializes in autonomous vehicles. “The environment is ever-changing: the snow has covered traffic signs; it’s raining on your windshield, the sun is blocking you. Our people train using these kinds of data.”
BAD TRAFFIC
Uskova asserts that technology tested in sun-drenched utopias can’t possibly translate to a city like Moscow. Gnarly road planning, terrible weather and reckless habits make the Russian capital one of the worst cities in the world for drivers.

With roads that spread like a cobweb away from the Kremlin, disturbances like car wrecks, construction and government motorcades can wreak havoc for miles. Seat belts are scorned, and traffic laws widely ignored; speeding violations are enforced with US$4 fines, paid by phone. It’s no surprise that Russia’s rate of road fatalities is nearly double that of the US, with an average of 20 serious accidents a day just in Moscow.
Or, for that matter, that dashcam videos of Russian road fights and collisions make up such a popular subgenre on YouTube.
But most of the world’s roads look more like Russia than Mountain View, and according to Uskova, that gives Russian developers an edge in building the brains of autonomous cars.

That theory was tested at a recent event in Moscow, advertised as the world’s first hackathon for driverless cars. In an austere, Soviet-era dormitory, top engineering students from far-flung schools like MIT, Cambridge and Peking University sank into beanbag chairs for a three-day coding binge.
“We’re here because it’s a chance to change the world over the next 10 to 15 years,” said Mitch Mueller, a student who traveled from the University of Wisconsin to compete. They were also competing for a cash prize, bragging rights and — most importantly — the attention of participating companies, including Uber and Nvidia, eager to recruit the next generation of AI talent.
MIMICKING THE BRAIN
The event had another purpose: to advance a credo that when it comes to autonomous cars, tougher conditions produce smarter technology. Lidar — the expensive, light-pulsing sensors relied upon by current autonomous car models — is worthless in snow and thus “a fake,” says Uskova. Instead, cars should be trained to operate using high-definition cameras, low-cost radars and powerful AI that mimics the human brain.
As the 150 engineers pored over Moscow road data, it was obvious that this vision is a long ways off. Most cars struggled to identify signs, for instance, which were hard to detect in snow or rain; and for non-Russian speakers, the task was practically impossible.
“The problem is that the signs are small, and in Russia they look very similar,” explained Sami Mian, a computer scientist at Arizona State University. “The main difference is numbers and arrows, and a city entry sign can look almost the same as a stop sign. The top team had 40 percent accuracy.”
That team, three local guys from Moscow, had tapped into a secret weapon: a trove of the popular dashcam footage, which had been harvested and stored at nearby Moscow State University. Derived from 100,000 dashcam videos, that data served as the building blocks of a basic neural network hammered out by the cigarette-puffing coders, who mentioned that they had slept a total of five hours over three days.
Russian-built autonomous systems are already in use by Kamaz, Russia’s largest truck maker, and an agricultural equipment company. Both are working with Cognitive Technologies to build autonomous machines. But adapting the technology for city use, and bringing it to the international stage, is a steep battle.
No government agency has developed regulations for autonomous cars, so road testing is constrained to designated testing zones. The only car testing zone in Moscow is a 400-meter track embellished with pedestrian crossings, road signs, markings and a section with circular traffic.
It’s a lousy facsimile of Moscow roads, or any road. But even worse is its location far outside the city center: a planned ride-along was scrapped because of bad traffic.
There was a time when Chinese master Yuan Shimao thought martial arts were all about punching and kicking. As a young practitioner, he focused on speed and strength. “I trained that way for many years without becoming still enough to search within myself,” said Yuan, who founded a kung fu academy in central China in 2004. “But as you gradually settle into stillness, you begin to understand what the scriptures mean by spirit,” he added. “You can begin to rediscover yourself.” That process is known as “entering the Dao” in martial arts. It is a guiding principle at Yuan’s academy in the sacred
The Nuclear Safety Commission (NSC, 核安會) on Sept. 24 approved the re-operation plan that Taiwan Power Co (Taipower, 台電) filed in March for the Ma-anshan Nuclear Power Plant in Pingtung County, after three rounds of review and 589 comments. Taipower now has to carry out the work in the plan and its own inspections on ageing, radiation and seismic resistance, then report back to the commission for review and on-site checks. Minister of Economic Affairs Kung Ming-hsin (龔明鑫) has named 2028 as the earliest restart. The NSC has given no date. THE DEBATE No challenge has been identified as to whether Ma-anshan
Oct. 12 to Oct. 18 After 11 years in prison on Green Island, Yen Shih-hung (顏世鴻) was finally due for release when a camp guard asked him for NT$20,000 to help pay his bride price. Yen refused. The next day, officials deemed that he had “failed to improve his thinking” and ordered him to undergo further political reeducation on Siaoliouciou (小琉球), where prisoners were also subjected to forced labor. He spent another 19 months there before regaining his freedom in January 1964. Yen’s punishment stemmed from his joining the Taiwan Provincial Student Affairs Committee
Cognitive warfare, says the Ministry of National Defense (MND), is the People’s Republic of China’s (PRC) use of “political, economic, cultural, military and legal means, with the intent to divide internal unity and undermine social stability” in Taiwan. Last week offered several examples. PRC media in October last year reported that the Chongqing Municipal Public Security Bureau had opened an investigation into Democratic Progressive Party (DPP) Legislator Puma Shen (沈伯洋), the DPP’s mayoral candidate for Taipei in next month’s election, for “Taiwan independence” activities. This was a cognitive warfare ploy, designed to unsettle the targeted person and to establish the idea
