Apps like Snapchat allows motorists to post photos that record the speed of the vehicle. The navigation app Waze rewards drivers with points when they report traffic jams and accidents. Even the game Pokémon Go has drivers searching for virtual creatures on the nation’s highways.

When distracted driving entered America’s consciousness, the problem was mainly people who made calls or sent texts from their cellphones. The solution then was to introduce new technologies to keep drivers’ hands on the wheel. Innovations since then — car Wi-Fi and a host of new apps — have led to a surge in connectivity in vehicles that experts say is contributing to a boom in highway deaths.

After steady declines over the last four decades, highway fatalities last year recorded the largest annual percentage increase in 50 years. And the numbers so far this year are even worse. In the first six months of 2016, highway deaths jumped 10.4 percent, to 17,775, from the comparable period of 2015, according to the National Highway Traffic Safety Administration.

After decades of steady declines, the number of deaths stemming from motor vehicle crashes has risen in the last two years to its highest level since 2009.  “This is a crisis with no resolution insight,” Gordon Fox from 2Pass Defensive Driving, an Arizona Based company said in an interview.

Most new vehicles sold today have software that connects to a smartphone and allows drivers to place phone calls, dictate texts and use apps hands-free. Ford Motor has its Sync system, for example. Others, including Honda, Hyundai and Mercedes-Benz, offer their own interfaces as well as Apple’s CarPlay and Google’s Android Auto.

Automakers say these systems enable customers to concentrate on driving even while interacting with their smartphones.

The data would say otherwise.
