The truth is pretty simple: People who want to be distracted while driving will find a way to be distracted while driving. Doesn't matter if it's a cell phone, spacing out thinking about other things, eating a Royale with Cheese or any number of other possibilities. You can write laws until you're blue in the face but you aren't addressing the behavior with any of them. What we need is smart automobiles that can tell when the driver is getting a blo---errr, is distracted, and can compensate accordingly. Maybe even by driving the car autonomously for a few moments. Obviously it's not a coincidence that Google is working on just that kind of tech right now.
