Toyota engineer warns automous cars could increase fuel use, urban sprawl
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.
The hypothesis is completely the opposite of how we generally think about autonomous vehicles, with some experiments showing fuel economy improvements by as much as 20 percent. However, Laberteaux is looking beyond one-off observations and extrapolating further. With the law still figuring out how to get driverless cars on the road, we're probably still decades from finding out what effects they will actually have on the world.
