'The Hop' Takes Suitcases Hands-Free {Gadling}

Oct 3rd 2012 11:20AM At least someone is thinking. I have tripped over those roller boards suitcases being dragged behind in crowded airports. It people could push them in front like a cart, they would have control and not swing them around making turns knocking into people. I realize no one has eyes on the back of their heads and are probably unaware of the damage they leave.
