This is what your phone will look like in the new Do Not Disturb While Driving mode that is coming with Apple's IOS 11 in the fall. A big black empty box. The DNDWD mode detects that you are in motion using WiFi doppler effect (why not the GPS?) then it turns everything off, no playing games or using apps. It also sends a reply to family and friends who text you that you are driving. According to Apple:
iOS 11 introduces a new way to help drivers stay more focused on the road with Do Not Disturb while driving. iPhone can detect when you may be driving and automatically silence notifications to keep the screen dark. Users have the option of sending an auto reply to contacts listed in Favorites to let them know they are driving and cannot respond until they arrive at their destination.
Apple has been sued a couple of times for not implementing this earlier, given that it got a patent for the technology in 2014, but does not say if this feature was added in reaction to the lawsuits. In the UK, the government is considering making "drive safe" modes mandatory. Fortunately nobody has sued them yet for distracted walking.
Anyone can override it by clicking on a button labelled "I'm not driving," which is supposedly for passenger use. And given how much time people spend stuck in traffic, I wonder how many people will click that button, how many people would go crazy having that blank screen on their phone, wondering what they are missing at every red light. How about you, would you use the Do Not Disturb While Driving mode? The poll is anonymous, be honest.
