Google Inc on Monday said that even self-driving cars that can sense and react faster than humans still wind up in accidents.
“We’ve been hit from behind seven times, mainly at traffic lights, but also on the freeway,” Chris Urmson, the head of Google’s autonomous car program, said in an online post. “We’ve also been side-swiped a couple of times and hit by a car rolling through a stop sign.”
Google self-driving cars, of which there are now more than 20, have been in 11 minor accidents in the six years since the project began, but they did not cause any of the crashes, according to Urmson.

None of the accidents involved injuries, Google said.
Google self-driving cars, which have “safety drivers” at the wheels to take over when deemed appropriate, have logged about 2.7 million kilometers, according to the California-based Internet titan.
“Even when our software and sensors can detect a sticky situation and take action earlier and faster than an alert human driver, sometimes we won’t be able to overcome the realities of speed and distance; sometimes we’ll get hit just waiting for a light to change,” Urmson said.
“And that’s important context for communities with self-driving cars on their streets; although we wish we could avoid all accidents, some will be unavoidable,” he said.
Google’s fleet of self-driving cars are averaging about 16,000 autonomous kilometers weekly, mostly on city streets.
“All the crazy experiences we’ve had on the road have been really valuable for our project,” Urmson said. “We have a detailed review process and try to learn something from each incident, even if it hasn’t been our fault.”
Non-profit organization Consumer Watchdog called for Google to release reports of accidents involving driverless cars in California so people can decide for themselves whether to trust the technology.
BUSINESS UPDATE: The iPhone assembler said operations outlook is expected to show quarter-on-quarter and year-on-year growth for the second quarter Hon Hai Precision Industry Co (鴻海精密) yesterday reported strong growth in sales last month, potentially raising expectations for iPhone sales while artificial intelligence (AI)-related business booms. The company, which assembles the majority of Apple Inc’s smartphones, reported a 19.03 percent rise in monthly sales to NT$510.9 billion (US$15.78 billion), from NT$429.22 billion in the same period last year. On a monthly basis, sales rose 14.16 percent, it said. The company in a statement said that last month’s revenue was a record-breaking April performance. Hon Hai, known also as Foxconn Technology Group (富士康科技集團), assembles most iPhones, but the company is diversifying its business to
Apple Inc has been developing a homegrown chip to run artificial intelligence (AI) tools in data centers, although it is unclear if the semiconductor would ever be deployed, the Wall Street Journal reported on Monday. The effort would build on Apple’s previous efforts to make in-house chips, which run in its iPhones, Macs and other devices, according to the Journal, which cited unidentified people familiar with the matter. The server project is code-named ACDC (Apple Chips in Data Center) within the company, aiming to utilize Apple’s expertise in chip design for the company’s server infrastructure, the newspaper said. While this initiative has been
GlobalWafers Co (環球晶圓), the world’s No. 3 silicon wafer supplier, yesterday said that revenue would rise moderately in the second half of this year, driven primarily by robust demand for advanced wafers used in high-bandwidth memory (HBM) chips, a key component of artificial intelligence (AI) technology. “The first quarter is the lowest point of this cycle. The second half will be better than the first for the whole semiconductor industry and for GlobalWafers,” chairwoman Doris Hsu (徐秀蘭) said during an online investors’ conference. “HBM would definitely be the key growth driver in the second half,” Hsu said. “That is our big hope
The consumer price index (CPI) last month eased to 1.95 percent, below the central bank’s 2 percent target, as food and entertainment cost increases decelerated, helped by stable egg prices, the Directorate-General of Budget, Accounting and Statistics (DGBAS) said yesterday. The slowdown bucked predictions by policymakers and academics that inflationary pressures would build up following double-digit electricity rate hikes on April 1. “The latest CPI data came after the cost of eating out and rent grew moderately amid mixed international raw material prices,” DGBAS official Tsao Chih-hung (曹志弘) told a news conference in Taipei. The central bank in March raised interest rates by
