I think it's possible for a passenger to be very distracting. But I would hope that most reasonable passengers would recognize when a driver needs to keep his eyes and ears on the road and converse accordingly. On the other side of the coin, passengers can be helpful in touchy situations by pointing out hazards, helping with blind spots, and whatnot. Of course, there's a line between what's helpful and what isn't. The habitual backseat driver isn't helpful. I think that one thing that's important to realize is that drivers aren't the best judges of whether or not they're distracted. They can recognize when something's really bad and say to themselves, "Hey self, I'm not paying attention to the road." But it likely takes a lot less than that to actually be distracted. I'm not suggesting that people cut out all hands-free calling. But I do think its use should be limited, and I think that some drivers could cut out many hours of calls. When I think of some of the phone conversations I overhear in public places, it becomes apparent that many calls can wait. My biggest complaint is when people feel that hands-free whatever is "safe." That's a false sense of security. Drivers need to realize that it's a distraction and that under certain driving conditions, the calls should wait. I agree that there's no excuse for not pairing a phone. It can easily be done via either the phone or radio. And because most car radios can handle multiple devices, it's an option even if you borrow someone else's vehicle. For those who truly can't handle it, go to the dealer or radio installer and let them do it. Interestingly, one writer suggests that the answer to all this technology is to have more technology. We now have cruise controls that adjust based on the speed of the car ahead. Crash sensors are coming into the picture. And backup cameras will be required in all vehicles starting in 2018. My personal issue is what to do about my two older cars. They drive like they're new, and I have no desire to replace them. One of them is old enough that it actually has a tape deck. I need to decide if it's a responsible expenditure to upgrade one or both of their radios to something that's appropriate to this decade.
