From the New York Times:
Anything that keeps tykes pacified on long car trips, like video systems in rear seats, is a boon to automotive safety. Today, Chrysler is poised to offer in its 2009 models a new entertainment option for the children: Wi-Fi and Internet connectivity. The problem is that the entire car becomes a hotspot. The signals won’t be confined to the Nintendos in the rear seat; front-seat occupants will be able to stay online, too.
Bad idea. As drivers, we have done poorly resisting the temptation to move our eyes away from the road to check e-mail or send text messages with our cellphones. Now add laptops.
