I would be in favor of it if it would only work for drivers, but it doesn't. I have an LG G3 with drivemode. It automatically comes on when you start driving. The problem is the lockout comes on when you're a passenger as well. So when the driver is panicking not being able to find a destination and you can't help them because your stupid phone is in drive mode, you really have to doubt the technology. Also, drive mode kicks on even when using the phone for google maps navigation!! Talk about going to a job interview in a city you've never been to and as soon as you enter the city your map goes away and suddenly all you see is "drive mode" on the screen. That would CAUSE more accidents than it would prevent because now I have to fiddle with the phone to disable drive mode and get my map back. And it will do it randomly, not right at the start of the trip, and ANY time during the trip.
