Toyota engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.

New Toyota semiconductors could increase hybrid fuel efficiency by 10%

Toyota may have an ace up its sleeve in the fuel economy wars, as it's developed a new type of semiconductor that will allegedly help the company's hybrids net a ten-percent improvement in fuel economy.
The tech is still in development, although Toyota is already reporting five-percent gains during testing, six years before it plans to implement the new semiconductor in production vehicles, meaning the ten-percent improvement doesn't seem like an untenable goal. That is, until you hear from Kimimori Hamada, the project general manager of Toyota's electronics division.
"We are aiming for great improvement in fuel economy and miniaturization," Hamada told Automotive News. "This is a very challenging target."

2013 Pikes Peak Hill Climb, Practice Day 3

The third practice day of the 91st Pikes Peak International Hill Climb is done. While the other classes got running time on the middle and top sections of the course, qualifying times were set on the bottom section of the course for the Open, Open Wheel, Electric, Exhibition and Vintage classes.
Everyone managed to keep it on the black stuff today, Greg Tracy setting the fastest time ahead of Hiroshi Masuoka, both men driving the Mitsubishi MiEV Evolution II four-wheel-drive prototype. Not even half a second behind Masuoka came Nobuhiro "Monster" Tajima in his Monster Sport E-Runner, who has taken about 18 seconds off his time since the first practice day. Rod Millen was the fourth fastest on the day in his Toyota TMG EV POO2.
Topping the Open Wheel class was Clint Vahsholtz, followed by Donner Billingsley, Andy Figueroa and Rodney O'Maley. The only driver in that class not to be given a time today was Dan Novembre. Kenshiro Gushi took the Exhibition class today as his Lexus IS F CCS-R made it up the mountain in 4:27.248, followed by Sage Marie in the Honda CR-Z at 5:19.591. Simon Pagenaud and his Honda Odyssey weren't classified.
