WELLINGTON, New Zealand (AP) — New Zealand on Sunday marked 100 days since it stamped out the spread of the coronavirus, a rare bright spot in a world that continues to be ravaged by the disease. Life has returned to normal for many people in the South Pacific nation of 5 million, as they attend rugby games at packed stadiums and sit down in bars and restaurants without the fear of getting infected. But some worry the country may be getting complacent and not preparing well enough for any future outbreaks. Prime Minster Jacinda Ardern’s leadership has been widely praised. Still, New Zealand’s international tourism industry has collapsed and the country remains more isolated from the outside world than before. 726

Waymo is starting to let the public take rides in its self-driving vans. This is the first commercial self-driving ride service to launch publicly, according to Waymo.For now, Waymo's definition of "the public" is a couple hundred pre-selected individuals in the Phoenix area. But Waymo is calling this is a small but important first step to launching an actual driverless ride sharing service.These initial users were all part of Waymo's "Early Rider" test program, so they've ridden in these vans before. The big difference is now they'll be allowed to invite others to ride with them — as many as four people can fit in the van — and they'll be able to speak publicly about the experience, including posting about it on social media.These customers will not be stepping into vans with empty driver's seats, though. While Waymo has given totally driverless rides to people as part of the private "Early Rider" program, for these more public rides, a Waymo employee will be in the driver's seat ready to take over if needed.Waymo is a subsidiary of Alphabet, Google's parent company.The service, called Waymo One, will operate 24 hours a day giving rides in the Phoenix area. Over time, the service will expand to cover more cities and be available to more riders than just the test group, Waymo CEO John Krafcik wrote in a blog post.Rides will be requested through an Uber-like smartphone app Waymo has created that will allow users to select pickup and drop-off locations and see a price estimate for the ride. The pricing strategy is part of what Waymo is working out with these more public rides. The pricing and software has been under development in the more secretive "Early Rider" program but will undergo more development in the public Waymo One program, a Waymo spokesperson said.Up until now, much of the research into autonomous driving has been around figuring out technical issues, said Karl Brauer, publisher of Kelley Blue Book and Autotrader. Waymo is taking another step in working through some of the other challenges, such as creating a service that's easy to use and meets riders' needs."Waymo's early rider program is allowing the company to identify these issues, and its new Waymo One service will expand the company's feedback system into a real-world business application," Brauer said. "In the race for the self-driving car, this information is invaluable."A company called May Mobility has been offering driverless rides to the general public in select Midwestern cities, but those rides have been on regular fixed routes in vehicles that travel no more than 25 miles an hour. 2613

  

WASHINGTON (AP) -- U.S. Navy leaders are recommending a sweeping list of changes in sailor training, crew requirements and safety procedures to address systemic problems across the Pacific fleet that led to two deadly ship collisions earlier this year that killed 17 sailors, according to a copy of the report obtained by The Associated Press.A critical report scheduled to be released Thursday calls for about 60 recommended improvements that range from improved training on seamanship, navigation and the use of ship equipment to more basic changes to increase sleep and stress management for sailors.Another Navy report released Wednesday concluded that three collisions and a ship grounding this year were all avoidable, and resulted from widespread failures by the crews and commanders who didn't quickly recognize and respond to unfolding emergencies. Navy leaders publicly acknowledged those failings in a congressional hearing last month.RELATED: San Diego sailors killed in ship collisionThe USS John S. McCain and an oil tanker collided near Singapore in August, leaving 10 U.S. sailors dead. And seven sailors died in June when the USS Fitzgerald and a container ship collided off Japan. The USS Lake Champlain collided with a Korean fishing vessel in May and the USS Antietam struck bottom near a shoal in Tokyo Bay.As a result of the two deadly accidents, eight top Navy officers, including the 7th Fleet commander, were fired from their jobs, and a number of other sailors received reprimands or other punishment that was not publicly released."We are a Navy that learns from mistakes and the Navy is firmly committed to doing everything possible to prevent an accident like this from happening again," Adm. John Richardson, the chief of naval operations, said in a statement Wednesday. "We will spend every effort needed to correct these problems and be stronger than before."RELATED: Remains of USS John McCain sailors recoveredRichardson ordered a comprehensive review of the accidents, led by Adm. Philip Davidson, head of the Navy's Fleet Forces Command. In a report spanning about 170 pages, Davidson notes that many of the lessons learned can be applied across the Navy. And he recommends the appointment of a senior Navy officer to oversee the implementation of the recommended changes across the fleet, both in the Pacific and -- where needed -- around the world.Proposed changes focused on five main areas: fundamental skills, teamwork, operational safety, assessment procedures and culture. Specifically, the recommendations include beefing up qualification standards for sailors who stand watch -- a key point of failure in the two deadly collisions. Others call for improved navigational skills and certifications for sailors, including better, more sophisticated training on radar, piloting, communications and other high-tech equipment.The report acknowledges the fast-paced operations in the Pacific region, where the Navy is faced with an aggressive China and a growing threat from North Korea's pursuit of nuclear weapons. And it notes that ongoing budget constraints make it difficult to meet the requirements in the very busy Pacific region."The ability to supply forces to the full demand is - and will remain - limited," the report said, adding that funding shortfalls for readiness across the Navy, "did have an impact in putting more pressure to meet increasing demand for Japan-based assets" without additional support from ships based in the United States.Faced with the increasing demands, there was less time for crew members to do needed training or certifications, the report said.The report also noted that despite the growing pressure and pace of operations, there was a "can-do" culture that persisted, and commanders failed to listen to their teams and were unable or unwilling to say no despite the risks."Can-do should never mean must-do so we must continue to encourage our commanders to accept the risks when the benefit to be gained is worth the potential risk of failure," the report said.A number of the recommendations points to fatigue and how the lack of sleep can lead to problems, particularly as sailors stand watch."Sailors need to know when they must succumb to their own fatigue, be proactive about their fatigue management plan, and reach out to leadership," the report said. It also suggested that a mentorship program be set up, assigning experienced commanding officers to help sailors develop leadership skills and focus on seamanship, navigation, team building and operational safety.Davidson's report was submitted to Richardson, and Navy officials said a number of the recommendations are already being addressed. 4693
