Ignorance and Bias About Self-Driving Cars

The National Association of City Transportation Officials (NACTO) has issued a policy statement regarding self-driving cars that betrays ignorance about the technology and bias against cars in general. This summary boils down the policy statement to five recommendations, a few of which make sense but most of which do not.

First, NACTO wants to forbid the use of partially automated vehicles on city streets, allowing them only on limited access highways. “Such vehicles have been shown to encourage unsafe driving behavior, with drivers reading more, texting more, and generally being inattentive while the vehicle is in motion.” Maybe so, but the real question is: do partially automated vehicles increase safety even if drivers are less attentive? Since partial automation measures (such as adaptive cruise control, lane keeping, and collision avoidance) are aimed mainly at increasing safety, banning them without considering the safety implications is being deliberately ignorant.

Second, they advise cities to “rethink. . . currently planned expressway expansions” that could become “white elephants” when self-driving cars effectively increase road capacities. The Antiplanner has actually offered the same advice, suggesting that new highways be built only where populations are growing rapidly. But the Antiplanner urges that the same advice be applied to transit projects, which are far more likely to become white elephants than highways, yet the city officials remain mum on this subject.
