Do Driverless Car Safety Features Merit Fuel Efficiency Credit?
That's Corporate Average Fuel Economy (CAFE), and meeting the stringent 54.5 miles per gallon by year 2025 target may be exceedingly difficult, particularly with low gas prices, so allowing credit for safety features like automatic braking and adaptive cruise control warrants merit, argues the Alliance of Automobile Manufacturers. "Fewer accidents will lead to less congestion and better traffic flow—factors that, when combined with speed management, could cut vehicle emissions by as much as 30%, say University of California at Riverside researchers," writes Mike Spector for The Wall Street Journal.
It's not a new argument. "In 2012, when setting new fuel-economy standards, regulators said safety features should be evaluated only on their ability to save lives or reduce injuries, and not be considered for mileage credits," writes Spector.
David Strickland, a former [National Highway Traffic Safety Administration] NHTSA head now practicing law at Venable LLP, said applying safety features could end up “watering down CAFE,” because quantifying their precise role is challenging. “It’s going to be very difficult to prove the amount of crashes avoided…that turns into the amount of congestion avoided that turns into the amount of fuel savings and emissions reduced.
We've seen this argument applied to traffic mitigation measures like traffic signal synchronization that planners argue reduce pollution by reducing the amount of time motorists sit behind red lights. But the argument can be made that smoother traffic flow makes driving more attractive compared to other modal alternatives, as Angie Schmitt of Streetsblog wrote on August 15, 2012.
NHTSA, which jointly sets CAFE standards with the Environmental Protection Agency (EPA), appears to show some willingness to consider the new safety features "ahead of 2017’s so-called midterm review of U.S. mileage standards."
New vehicle sales data for February shows average fuel economy of 25.2 mpg, "according to figures from the University of Michigan Transportation Research Institute," writes Spector. "That’s down modestly from January as low gas prices send consumers flocking to less-efficient pickup trucks and sport-utility vehicles."
