I've been seeing that, and I can see the convenience and desirability . I have no idea how its supposed to make anything less distracting.
I used tailgate minivans at night to watch the video player through their back window.
Haha, I've done the same depending on what they are watching. I get wifi in the vehicle for the amusement of kids on long trips or for business, which I would think and hope was the intended use...but its a persons choice let themselves become distracted.
It all boils down to people not understanding that driving is a major task and not taking it seriously.
