Phone Makers Could Cut Off Drivers. So Why Don’t They?

In Apple’s case, the evidence shows, the company has a patent for technology designed to prevent texting while driving, but it has not deployed it.

.. Generally, companies have taken the position that text-blocking technology is embryonic and unreliable. They argue that they cannot shut down a driver’s service without the potential of mistakenly shutting off a passenger’s phone or that of someone riding on a train or bus.

.. Even if the technology worked to perfection, would people accept having their service blocked? After all, the idea of mobile phone service is to let people communicate on the go.

.. Apple says it has taken other steps to address distracted driving. Its CarPlay integrates with some cars so drivers can use voice commands to control some functions of the car and the phone, including letting them orally compose text messages and listen to incoming ones. The technology, Apple says, “allows you to stay focused on the road.”

.. Further, she said, it wouldn’t make sense to turn off all phone functions, like maps or navigation, that drivers rely on.
