Tests with Apple‘s (NASDAQ:AAPL) iPhone and mobile devices running Google‘s (NASDAQ:GOOG) Android OS showed the the performance of drivers declined equally with voice-to-text applications and manual text entry, the Washington Post noted.
Subjects in the tests were asked to drive on a closed course while text-messaging through both voice and manual methods. The researchers measured the amount of time the drivers’ spent watching the road, their devices, and a test light in the car.
The researchers said that anything that distracts a drivers’ attention was likely to degrade their driving performance.
Every day, Americans send 6.1 billion text-messages. Roughly 3,300 people are killed in auto accidents that are linked to distracted driving. 39 states have prohibited the texting on mobile devices while driving.
