Accidents are going to occur no matter how cognizant one is behind the wheel. Few of us concentrate as much as we should while driving. Listening to our favorite tunes over stereo systems often better than those in our homes, conversing with passengers or just thinking about where to stop for dinner conflict with the concentration that should be geared to safe driving. All too often I have seen people grooming themselves, eating and even reading a book as they drive down an interstate.
Technology has created automobiles that are so comfortable, that handle so well that we sometimes forget we are controlling two or more tons of metal that can create havoc in a split second when there is loss of control. In the early years of our love affair with automobiles and up through the fifties, controlling vehicles without power steering and brakes often took near brute strength. Doing much of anything but driving was difficult at best.
There is a great difference between talking on the phone--hands-free--or not and taking your eyes off the road to enter a text message or find an address on a GPS app. Some years ago one of the auto manufacturers experimented with H.U.D. (heads-up displays). Instead of looking down at your speed and other data, like a jet pilot, an image of the instrument cluster was projected onto the lower portion of the windshield allowing the driver to keep his eyes on the road while still allowing them to gather information as needed.
I think...like the H.U.D. concept, the key is to remain alert at all times and by all means keeping one's eye on the road. I would recommend any driver when at all possible take the time to pull to the side of the road or to another safe parking environment to make or receive calls. Just common sense...like eating, drinking, shaving or reading War & Peace...pull over!
