SAN FRANCISCO (AP) — The robotic car company created by Google is poised to attempt a major technological leap in California, where its vehicles will hit the roads without a human on hand to take control in emergencies.The regulatory approval announced Tuesday allows Waymo's driverless cars to cruise through California at speeds up to 65 miles per hour.The self-driving cars have traveled millions of miles on the state's roads since Waymo began as a secretive project within Google nearly a decade ago. But a backup driver had been required to be behind the wheel until new regulations in April set the stage for the transition to true autonomy.RELATED: 2018 could be a pivotal year for driverless carsWaymo is the first among dozens of companies testing self-driving cars in California to persuade state regulators its technology is safe enough to permit them on the roads without a safety driver in them. An engineer still must monitor the fully autonomous cars from a remote location and be able to steer and stop the vehicles if something goes wrong.California, however, won't be the first state to have Waymo's fully autonomous cars on its streets. Waymo has been giving rides to a group of volunteer passengers in Arizona in driverless cars since last year. It has pledged to deploy its fleet of fully autonomous vans in Arizona in a ride-hailing service open to all comers in the Phoenix area by the end of this year.But California has a much larger population and far more congestion than Arizona, making it even more challenging place for robotic cars to get around.RELATED: NTSB report: Uber self-driving SUV saw pedestrian in Arizona but didn't brakeWaymo is moving into its next phase in California cautiously. To start, the fully autonomous cars will only give rides to Waymo's employees and confine their routes to roads in its home town of Mountain View, California, and four neighboring Silicon Valley cities — Sunnyvale, Los Altos, Los Altos Hills, and Palo Alto.If all goes well, Waymo will then seek volunteers who want to be transported in fully autonomous vehicles, similar to its early rider program in Arizona . That then could lead to a ride-hailing service like the one Waymo envisions in Arizona.But Waymo's critics are not convinced there is enough evidence that the fully autonomous cars can be trusted to be driving through neighborhoods without humans behind the wheel.RELATED: Potential "game changer" could make commutes more relaxing"This will allow Waymo to test its robotic cars using people as human guinea pigs," said John Simpson, privacy and technology project director for Consumer Watchdog, a group that has repeatedly raised doubts about the safety of self-driving cars.Those concerns escalated in March after fatal collision involving a self-driving car being tested by the leading ride-hailing service, Uber. In that incident, an Uber self-driving car with a human safety driver struck and killed a pedestrian crossing a darkened street in a Phoenix suburb.Waymo's cars with safety drivers have been involved in dozens of accidents in California, but those have mostly been minor fender benders at low speeds.RELATED: Waymo self-driving car crashes in ArizonaAll told, Waymo says its self-driving cars have collectively logged more than 10 million miles in 25 cities in a handful of states while in autonomous mode, although most of those trips have occurred with safety drivers.Waymo contends its robotic vehicles will save lives because so many crashes are caused by human motorists who are intoxicated, distracted or just bad drivers."If a Waymo vehicle comes across a situation it doesn't understand, it does what any good driver would do: comes to a safe stop until it does understand how to proceed," the company said Tuesday. 3827

SAN YSIDRO, Calif. (KGTV) - Customs and Border Protection officials tweeted thermal camera video Friday of men climbing the U.S.-Mexico border fence and damaging the concertina wire.The video was recorded by U.S. Border Patrol cameras placed near Border Field State Park in Imperial Beach, opposite from where migrants have been gathering as more members of the Central American caravan arrive in Tijuana.There was no word on whether the incident captured on video led to an arrest.“All seeking to enter the U.S. are urged to do so at one of more than 320 official U.S. Ports of Entry,” Customs and Border Protection officials wrote in the tweet.  665

SAN YSIDRO, Calif. -- A quick conversation with a customer is now a rare interaction for border town business owner Sunil Gakhreja.“There is no business. You’ve been in here for 20 minutes and no one’s come in, no one’s even crossed by in front of us,” said Gakhreja.The Department of Homeland Security banned all non-essential travel between the United States and Mexico because of COVID-19.For business owners in the small border town of San Ysidro, about 20 minutes south of San Diego, this closure is suffocating their livelihood.“When they close the border, economically, it affects us a lot. That’s our main bread and butter,” said Gakhreja.The San Ysidro Chamber of Commerce said 95% of the customers in the stores cross the border from Mexico into the U.S. to shop.The chamber reports now that border crossings are restricted—businesses are losing .8 million per day.Gakhreja is no exception. He was forced to lay off the entire staff at his perfume shop.“It’s only me and my wife working. That’s how we can survive.”The family’s entire livelihood hangs on the success of one strip mall on San Ysidro Boulevard. They just opened a pizza shop next door named for Gakhreja’s mother Maya.It’s a tribute he’s desperately trying to keep alive.“We put everything— our soul in there, our money, every single penny we have. I don’t want to let it go down, in any way,” he said.Sunil has been in the United States for more than two decades after immigrating from India.He said this city gave him the chance for a different life than he had growing up.“This country has given me everything,” said Gakhreja. “I am here because of this community. This border town has given me everything: the ability to buy my house, to run my business, I couldn’t be more blessed, but I don’t want to give up my hope. I want to hold on to that last breath that we have.”The San Ysidro Chamber of Commerce is handing out PPE to help small businesses hold on. Packages of hand sanitizer, masks, face shields and gloves will go out to any business that needs it.“Being safe, PPE, distancing ourselves, wearing our masks, that’s the way to protect ourselves,” said Jason Wells of the San Ysidro Chamber of Commerce. “Not being xenophobic and doing things like closing the border.”Gakrehja said this street on the border can’t wait too much longer.“You’re going to lose jobs, people will go into depression, this is our American dream,” he said.Gakrehja is just hoping lawmakers see one thing: in times of turmoil—keeping people apart can cause great pain.“We have to understand we are a great nation, but at this time we need other people’s help too,” he said.The border closure is extended until July 22, 2020. However, for the past several months, the deadline has been extended several times. Business owners fear that will continue to happen. 2833

SAN FRANCISCO (AP) — Schools across the United States are facing shortages and long delays in getting laptops and other equipment needed for online learning. They are this year’s most crucial back-to-school accessories. Part of the reason is high demand and disruptions of supply chains that have jammed production of laptops and Chromebooks made by Dell, HP, Lenovo and other brands. Schools say another critical reason is the Trump administration’s recent sanctions on Chinese companies that have exacerbated massive backlogs. Educators nationwide worry that computer shortfalls will compound inequities. They also warn of headaches for students, families and teachers. 679
