Death by Cell Phone App

The Antiplanner has previously noted the frightening increase in highway fatalities in the last few years and suggested it might be related to growing traffic congestion. An alternative view is presented in a new paper by researchers at Purdue University titled “Death by Pokémon Go.” The paper found that the release of the Pokémon Go game led to a “disproportionate increase in vehicular crashes and . . . fatalities in the vicinity of locations, called Poke?Stops, where users can play the game while driving.”

After mysteriously collapsing by 25 percent between 2005 and 2010–the biggest five-year decline in 60 years–the number of fatalities remained roughly constant at around 32,500 for five years. But between 2014 and 2016, they grew by 15 percent, or nearly 4,800 deaths. While one computer game isn’t responsible for all 4,800 deaths, the study suggests that the growth of cell phone apps–from 800 iPhone apps in 2008 to more than 2 million today–and related distracted driving could be responsible for much of the increase.

Comparing 2016 fatalities with those from 2005 shows a 14 percent decline overall. However, the decline for occupants of motor vehicles is much larger, while non-occupant fatalities actually increased. Continue reading


Making Both Autos and Highways Safer

New York Times columnist David Leonhardt writes that “America is now an outlier on driving deaths.” He is partly right and partly wrong.

He is right that auto fatality rates per billion vehicle miles in the United States are a little higher than in many other countries and that highway safety has grown in other countries faster than in the U.S. But this is because roads elsewhere were far more dangerous than they have been in the United States for a long time. The reality is that other countries have caught up with the U.S., not that the U.S. has fallen behind.

For example, according to data published by the OECD, in 1990 Austria suffered 32 deaths per billion vehicle kilometers compared with just 13 in the U.S. By 2014, Austria’s fatalities had fallen to 5.4, while the U.S. had fallen to 6.7. Yes, Austria’s had fallen more but only because they were so bad in the first place. Continue reading


Will Trump Kill V2V Rule?

One of the many proposed rules published a few days before President Trump took office was a mandate that all cars built after 2020 come with dedicated shortrange radio communications (DSRC) so that they can talk with one another. According to the National Highway Traffic Safety Administration (NHTSA), this rule will “prevent hundreds of thousands of crashes.” The rule is downloadable as a 166-page Federal Register document or a slightly more readable 392-page paper.

The mandate would add about $300 to the cost of every car, or several billion dollars a year. The radios would not add much weight to the cars, but once most cars have them the collective weight would increase fuel consumption by more than 30 million gallons a year.

In exchange for these costs, NHTSA estimates that the rule will save 23 to 31 lives by 2025. These numbers are small because the benefits of vehicle-to-vehicle (V2V) communications are nil unless both vehicles in a potential communication have them. Since the average car on the road is more than 11 years old, it will take about that many years before most cars have V2V and many more years before nearly all cars have it. Yet even by 2060, NHTSA projects the technology will save only 987 to 1,365 lives.

Traffic Fatalities Up Nearly 8 Percent in 2015

The National Highway Traffic Safety Administration (NHTSA) estimates that 35,200 people died in motor vehicle accidents in 2015, a 7.7 percent increase from 2014. This increase is a result of a combination of a 3.5 percent increase in vehicle miles of travel plus a 4.1 percent increase in fatalities per billion miles traveled.

The 32,500 number is a “statistical projection,” not an exact count, which won’t be available until this fall. NHTSA’s previous statistical projections have been fairly accurate; the estimate for 2014 turned out to match the final number exactly, while the average for the previous six years was off by only 26. The worst was in 2012, when the projection was 298 too high.

According to NHTSA’s estimate, fatalities increased the most in the Northwest (Alaska, Idaho, Montana, Oregon, and Washington), with a 20 percent gain. Fatalities declined 1 percent in the South Central region (Louisiana, Mississippi, New Mexico, Oklahoma, Texas), while they grew from 4 to 10 percent in the rest of the country.

Safety vs. Fuel Economy?

Robert Norton is a former attorney with Chrysler, so he must know cars, right? Apparently not, for his recent National Review On-Line article about auto safety misses the mark.

Norton frets that Obama’s fuel economy standards, which require that the average car sold in 2025 gets 52 mpg, will lead to dangerous cars. His evidence is a thought experiment.

“Imagine a head-on collision,” he says, of “a Cadillac Escalade and the other a Chevy Volt. Which would you want to be in?” He thinks it is obvious that anyone would want to be in the Escalade. Yet many small cars are considered safer than many larger vehicles.
