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.

Does Scion's LA concept presage a US Auris?

When the doors open at the LA Auto Show in a few weeks, Scion will be on hand to showcase its new iM Concept. But considering what little Toyota's youthful brand has revealed about the concept so far, it's led to rampant speculation. And the prevailing wisdom seems to point towards a production iM arriving as a Scion-badged version of the Toyota Auris.
For those unfamiliar, the Auris is to European (and other) markets essentially what the Matrix is (was?) to ours: a hatchback version of the Corolla. The model line was first introduced in 2006, looking in its first iteration like an overgrown version of the contemporary second-gen Yaris, and was replaced with the current model in 2012. It's available as a five-door hatch or wagon, with a range of gasoline, diesel and hybrid powertrains available.
If the rumors - spurred by the similarity of the iM concept's nose depicted in the teasers - prove accurate, and public reception to the idea ends up spurring Toyota to put it into action, it wouldn't be the first overseas Toyota brought over as a Scion. The Scion iQ was sold as the Toyota iQ overseas years before it arrived here.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
