Hundreds of Detroit residents line up to ride in autonomous cars

DETROIT — Members of the public got the chance Friday to take a free ride in a self-driving vehicle as part of an effort to clear up confusion about the technology. Hundreds signed up for the 6-minute journey that led riders through a course set up inside a Detroit convention center. Mary Van Der Maas heard about the opportunity on the radio and decided to give it a shot. The 73-year-old retiree from Grosse Pointe, Michigan, hopped into an autonomous Chrysler Pacifica Hybrid minivan, and off she went. "I think that it's just ignorance that keeps us from wanting to do this. And once you experience it, it's marvelous," she said afterward. Daniel Schroeder, 17, said he "thought it was interesting how the car knew its route." "And then it could identify things in the road," said the high school junior from Troy, Michigan, who spent one of the days of his spring break at the demo inside Cobo Hall downtown. Rep. Debbie Dingell also rode in the driverless Pacifica, asking more than a few questions of organizers along the way. "Public confidence in autonomous vehicles has decreased, not increased, over the last year for a variety of reasons," the Democratic congresswoman said. "And people need to get to know it. They need to be hands-on. They need to see that it works." Dingell said she had asked her husband, the late John Dingell, the longest-serving member of Congress in the institution's history, to serve as an advocate for driverless cars, citing the technology's potential to benefit older Americans. "He just quite frankly didn't trust it," Debbie Dingell said. Technological hurdles and apprehension have limited attempts to deploy fully autonomous vehicles on public roadways. Uber pulled its self-driving cars out of Arizona last year after one of the ride-hailing service's autonomous cars struck and killed a woman as she crossed the street. Mary Moore of SAE International, an association of mobility engineers, said the idea behind the Detroit event is to "use the facts, use what's on the market today to explain what the capabilities are today and then also give a glimpse into what can happen in the future." The event was sponsored by SAE International as well as Partners for Automated Vehicle Education, a coalition of industry, nonprofit and academic institutions whose goal is to inform and educate the public and policymakers about automated vehicles. It runs through Sunday and is free to attend.

Ford, Chrysler and Mazda expand scope of Takata airbag recalls

The scope of the Takata airbag inflator recall is ballooning once again across the United States. Where Honda has elected to take its driver-side airbag campaign nationwide, Chrysler Group and Ford have now announced expanded regional actions to cover some passenger-side airbag inflators. Mazda is adding more regions, as well. For Chrysler Group, the campaign covers the inflators on 149,150 examples of the 2003-model-year Ram 1500, 2500 and 3500 pickups. The recall is limited to vehicles sold or ever registered in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, Texas and the territories of American Samoa, Guam, Puerto Rico, Saipan, and the Virgin Islands. The company will begin notifying affected customers on January 19. According to Chrysler's announcement of the action, the passenger side inflators in these trucks "are of a type that is not used in any of the other vehicles affected by Chrysler Group's regional field action." The automaker says that it's not aware of any actual failures or accidents in these pickups and even claims there are no "observed failures in laboratory testing of its airbag modules." The company is continuing to study the problem, though. Ford is taking a similar step by issuing a recall of inflators for 38,500 examples of the 2004-2005 Ranger and 2005-2006 Ford GT. The campaign only affects vehicles originally sold or ever registered in Florida, Hawaii, Puerto Rico and the US Virgin Islands. Certain zip codes of Georgia, Alabama, Mississippi, Louisiana, Texas, Guam, Saipan and American Samoa are also covered. There's already precedent for passenger-side airbags to be covered under the Takata inflator recall. When many automakers announced campaigns in June, BMW, Chrysler, Ford, Honda, Mazda, Nissan and Toyota all included that side in some of their repairs. Subaru subsequently did, as well. In addition, Mazda is expanding the scope of its recall to add Florida, Puerto Rico, Hawaii, Saipan, Guam, American Samoa, US Virgin Islands, Georgia, Alabama, Louisiana, Mississippi and Texas to the affected areas. The company estimates that it has a total of 86,773 vehicles in need of repair. Mazda is also teaming with Toyota to begin independent testing of the Takata inflators. Scroll down to read all of the automakers' announcements of these newly expanded recalls. Statement: Air-Bag Inflators December 3, 2014 , Auburn Hills, Mich.

An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.
