The German city of Augsburg has already tried putting traffic lights in the ground to keep cellphone-obsessed pedestrians from walking on to train tracks, but the Australian state of New South Wales wants to take things one step further. It tells Mashable that it's going to install ground-based traffic lights at key crosswalks in Sydney (likely in its central business district) as part of a trial starting in December. The aim, unsurprisingly, is to prevent an unpleasant encounter with a car while you're busy texting your friends.
