NHTSA investigating 561k Toyota Prius hybrids for possible steering shaft defect

The Detroit News is reporting that the National Highway Traffic Safety Administration will investigate some 561,000 Toyota Prius models for potentially defective steering shafts. The affected hybrid models are from the 2004-2009 model years. The story indicates that NHTSA is weighing whether or not to grant a defect petition, which claims that Toyota incorrectly assembled the hatchback's steering linkage.
As of this writing, there is no recall. However, a recall based on the Prius steering shaft would be the third related to steering issues for the model since 2006. Seven years ago, Toyota recalled 170K Prius models for potential cracking of the intermediate shafts, and in November of 2012, the automaker recalled 670K units to replace the steering shaft extension assembly.
We'll be monitoring NHTSA's signals to see if this investigation turns into a full-fledged recall. For now, stay tuned.

Lexus LFA prototype spied lapping the Nurburgring with new bodywork

The Lexus LFA was a real engineering tour de force. Sure, it was stuck in development hell for years, and the 4.8-liter V10's 552-horsepower output wasn't super impressive when it came out, but it integrated a ton of expertise Toyota gained from its F1 team in the early to mid 2000s. Unfortunately, it didn't sell well. Last year, we found there were a few new models sitting on dealer lots, five years after the 500-model run ended. Still, it looks like Toyota may not have given up on the idea of a race-derived flagship for Lexus, at least based on this prototype running around the Nurburgring this week. At first glance, the car pictured here looks like an LFA with the Nurburgring Package and some camouflage on the front and rear fenders. If you look closely, you can see that the fenders are significantly wider than on the standard LFA. Based on the license plate, this appears to be the same car with two different sets of wheels. Lexus may simply be swapping out worn tires, or they may be testing different wheel and tire combinations to fit the wider wheel wells. Anything beyond this is just speculation. There have been rumors of a new flagship Lexus sports car that sits atop the LC 500 and LC 500h. We saw the Toyota GR Super Sport Concept back in January, though that car looks nothing like what we see here. As much as we would love that sweet Yamaha co-developed V10 to carry over, we're not holding our breath. Some sort of hybrid powertrain is almost a certainty. Maybe Lexus and Toyota could pull some tech from its Le Mans-winning TS050 Hybrid race car. Related Video:

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.
