5. Heads-up displays: This technology is so new, we're not prepared to make a call on it just yet. However, as beautiful as tech like the Mercedes-Benz augmented reality windshield may be, it seems a little intrusive.
6. Autonomous vehicles: This is the holy grail of vehicle technology, and if/when it rolls out, it would effectively make distracted driving a non-issue. We'll tell our cars where we want to go, and they'll get us there, while we kick back and enjoy a nice half hour of Farmville. Or a nap.
Google is testing its autonomous vehicles now, and other rides -- like GM's EN-V concept -- have similar technology embedded. But self-driving vehicles are a long way off. Not only does the technology require a lot of development, but roadways require a good bit of infrastructure improvements. After all, in order for cars to know when to slow down in traffic, they'll need to have an idea of when traffic lights are changing, to know when emergency vehicles are approaching, and so on.
As you can see, there's no perfect solution to the problem of distracted driving -- not yet, anyway. For now, the best we can do is to be aware of the dangers and to exert some self-control by putting our phones, tablets, and other distractions away.
