Waymo partners with Nissan, Renault on robotaxis outside U.S.

SAN FRANCISCO — Self-driving car pioneer Waymo is teaming up with automakers Renault and Nissan to make its first journey outside the U.S. with a ride-hailing service that will dispatch a fleet of robotaxis in France and Japan. The partnership announced late Wednesday underscores Waymo's ambition to deploy its driverless technology throughout the world in an attempt to revolutionize the way people get around. The Mountain View, California, company can afford to try because it's backed by one of the world's richest companies, Google, which secretly began working on driverless technology a decade ago before spinning off that project into what is now known as Waymo. After launching its ride-hailing service in France and Japan, Waymo intends to explore other European and Asian markets with Renault and Nissan. "This is an ideal opportunity for Waymo to bring our autonomous technology to a global stage," Waymo CEO John Krafcik said. Waymo, Renault and Nissan didn't set a timetable for when their ride-hailing service will launch. They left most other details vague. It seems likely it will still be several years before Waymo will be in a position to pose a serious challenge to Uber, the world's largest ride-hailing service. Although Waymo's self-driving technology is widely considered to be the world's most advanced, it still isn't adept enough to be trusted without a human poised to take control in case something goes awry with the robot. Waymo had hoped to launch a fully autonomous ride-hailing service last year in the Phoenix area, but instead is still keeping human safety drivers in those vehicles more than six months after it rolled out. That service, known as Waymo One, is still only offering rides to a few hundred passengers that previously participated in a test program. Krafcik told the German newspaper Handelsblatt last year that Waymo will likely use a different brand for its ride-hailing services outside the U.S. That could be one reason Waymo is working with France-based Renault and Japan-based Nissan, household names in their home countries. Waymo has previously struck deals with two automakers, Fiat Chrysler and Jaguar, but those involved ordering tens of thousands of vehicles to be equipped with self-driving technology for services in the U.S. So far, Waymo is only using Fiat Chrysler minivans for its Phoenix service. The partnership with Renault and Nissan also involves a long-time alliance they formed with Mitsubishi.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.
