Toyota's Bob Carter says far fewer stations needed in shift from gas to hydrogen

Toyota's Bob Carter has been talking about green cars for years, but it's only been recently that his comments have really caught widespread attention thanks to his disparaging remarks about electric vehicle supporters like Elon Musk and Carlos Ghosn and optimism about hydrogen. Speaking at the opening of the Chicago Auto Show this morning, Carter said that Toyota has claimed the "pole position on CAFE," thanks to its deep hybrid bench. The company's green car cred will continue to grow because of its upcoming hydrogen fuel cell car, due out next year. Carter is relentlessly optimistic: "I truly believe fuel cells will fundamentally change how we feel about transportation," he said. The reason, Carter said, is that a hydrogen infrastructure will be easier to install than people think. He referenced a study conducted by the University of California (which we've heard about before) that found that California would only need 68 hydrogen stations to refuel the roughly 10,000 H2 vehicles that Toyota hopes to sell in by 2016 or so. That's a lot more than the nine that exist today, but the state has already approved funding for 20 new stations by 2015 and then up to 100 by 2024. Then he said this: "If every vehicle in California ran on hydrogen, we could meet refueling logistics with only 15 percent of the nearly 10,000 gasoline stations currently operating in the state." "We could meet refueling logistics with only 15 percent of gasoline stations currently operating in CA" - Bob Carter This made us wonder: if the refueling time and range are roughly equivalent between hydrogen and gasoline – Toyota's hydrogen car is supposed to be able to go 300 miles on a five-minute fill-up - then why has the market decided that there should be 10,000 gas stations in California and why would 1,500 be sufficient for hydrogen? "If the locations are optimized," he said, "we don't need 10,000 stations." For example, at major intersections, instead of three gas stations, you'd really just need a single hydrogen one. "There are a lot of questions about the infrastructure, but it's coming. ... It's a hurdle that we've got to climb but it's not as steep as some may imagine." Toyota's Mike Michaels, the national manager, media and public affairs at Toyota Motor Sales, then stepped in to point out that there are gas stations closing and admitted that there might be too many gas stations in California.

Hello, Siri? Please don't crash the car

Hands on the wheel and eyes on the road? You could still be distracted while driving. Voice-recognition software that many automakers tout as a safer alternative to handheld devices can still divert drivers' attention, a new study published by AAA found. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri. The technology is alluring because it allows drivers to do things like change the radio station or compose a text message without removing their hands from the wheel or their gaze from the road. But many of those tasks increase a driver's cognitive workload. Depending on the situation, that can be dangerous. "It's especially problematic, because you can be distracted and not know it," J. Peter Kissinger, president of the AAA Foundation for Traffic Safety, told Autoblog. "That's the nature of mental distraction. It's hard to appreciate. ... Often, you don't know you're distracted until it's too late." There's significant variation in the results of the study. Simple, single-task car commands for operations like changing the radio station caused minimal increases in workload, about the same as listening to an audio book. Composing information using speech-to-text technology was more burdensome, and using menu-based functions caused a high level of cognitive workload. Siri-based interactions posed the highest levels of distraction, according to AAA. Researchers noted that workload ratings were the highest on their scales when participants in the study used Siri, and two of the three simulator crashes they observed during the study of 36 participants came while the subjects were interacting with Siri. The subjects weren't looking at nor making contact with their iPhones during these interactions. "Common issues involved inconsistencies in which Siri would produce different responses to seemingly identical commands," the researchers wrote. "In other circumstances, Siri required exact phrases to accomplish specific tasks and subtle deviations from that phrasing would result in a failure. ... Some participants also reported frustration with Siri's occasional sarcasm and wit." It wasn't just the complexity of the task that caused variations in level of distraction – the variations could also be dependent on the particular make and model of the car being tested.

Toyota still wants Tesla's battery help, still evaluating RAV4 EV program

Tesla Motors said earlier this month that the agreement it has with Toyota to supply battery packs for the Toyota RAV4 EV SUV would be finished by the end of the year. The deal is done, but Toyota is now singing its best version of Baby, Please Don't Go. The Japanese automaker may look to extend the battery-pack agreement with California-based Tesla, Automotive News says, citing comments made by Osamu Nagata, who heads Toyota's manufacturing and engineering in North America. Nagata also complimented Tesla for its "clear business strategy." Toyota, which owns 2.5 percent of Tesla, started the RAV4 EV collaboration in 2012, in which Tesla was to make about 2,600 battery packs for the all-electric SUV. That agreement was estimated to be worth about $100 million. "We are also evaluating the RAV4 EV program and will have more to say at a later date" – Toyota "We have a good relationship with Tesla and will evaluate the feasibility of working together on future projects," Toyota said in a statement e-mailed to AutoblogGreen. "We are also evaluating the RAV4 EV program and will have more to say at a later date." And while Toyota hasn't quite met initial sales expectations – it sold about 1,600 of the RAV4 EVs through this spring – the company expects to reach 2,500 by the end of the year. And the partnership did generate about $15 million in revenue for Tesla, according to that company's first-quarter letter to shareholders. That said, Tesla is obviously focusing its battery-making efforts on its own models.
