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

Scientists have discovered a pocket sized dinosaur forerunner that was just 4 inches tall. Named Kongonaphon kely, which means tiny bug slayer, the creature looked like a dinosaur but scampered the Earth earlier, predating both dinosaurs and flying pterosaurs. The fossils, dug up in Madagascar, date from 237 million years ago, according to a study Monday in the journal Proceedings of the National Academy of Sciences. 429

SAN FRANCISCO (AP) — The amount of snow blanketing the Sierra Nevada is even larger than the 2017 snowpack that pulled the state out of a five-year drought, California water officials said.As of Thursday, the snowpack measured 202% of average after a barrage of storms throughout winter and spring, according to the Department of Water Resources.The wet weather has slowed but not stopped, with thunderstorms prompting flash flood warnings Sunday in the central and southern parts of the state.At this time last year, the snowpack measured 6% of average — making this year 33 times bigger than 2018, the San Francisco Chronicle reported.In 2017, the snowpack measured 190% of average.The snowpack supplies about 30 percent of state water needs.In the Tahoe Basin, Squaw Valley ski resort has seen so much snow it plans to keep its slopes open until least July 5. In May alone, Squaw recorded 37 inches (94 centimeters).State officials consider the most important snowpack measurement to be the one taken around April 1 because that's typically when storm activity subsides."And then after that the sun's highest position in the sky contributes to rapid melting. This year, that didn't happen and we had late season snow," National Weather Service forecaster Idamis Del Valle told the newspaper.This year's April 1 reading put the snowpack at 176% of average, making it the fifth-largest on that date, with records going back to 1950, the Chronicle said.___Information from: San Francisco Chronicle, http://www.sfgate.com 1528

SARASOTA Co., Fla. — A brawl between two moms at a school bus stop landed both in the hospital.One of those mothers was Tiffani Cruz. She was recently released from the hospital.“It was self-defense over an incident that made no sense," she said.While North Port Police say it started over an argument about parenting, Cruz claims she and the other mother have had issues before. She says two weeks ago, she confronted that mom for yelling at another child at the bus stop. But Tuesday morning, their verbal arguments went too far.“My heart was racing!” said Eithan Cruz, who is of no relation to Tiffani Cruz. The child and his brother, Bairon Velazquez, witnessed the fight from the back window of their school bus.“Her face was bleeding and stuff,” Eithan said.“I looked away," Bairon said..Cruz admits she hit the other mom with her mug. Police have not identified the other woman. “I went to run and that’s when she picked up the glass, ran at me and stabbed me twice in my arm, once at my wrist and in back of my shoulder," Cruz said.Both parents ended up in the hospital, but paramedics airlifted the other woman to the hospital with a serious cut to her throat.“She got this close to my face nudged me with her nose and when she nudged me with her nose— it was her fist going up so my fist was going up," Cruz said when asked why she felt she acted in self-defense.Sarasota County Schools is offering counselors after several dozen elementary-aged students witnessed the violent fight.“I regret the whole incident, there’s no reason it should have happened. We’re adults," Cruz said.Investigators say charges are pending.  1678
