In early colonial America, port cities often implemented cobble stone streets. While today, such paths are romanticized, they were originally paved to improve the traction of a horse’s hooves with the ground. As a beast of burden at the time, the horse helped carry massive loads of cargo and the cobble stone streets gave hooves more pushing power. > Much more recently, major cities have adapted to the ubiquity of smart phone technology. New York City replaced telephone booths with charging stations and Wi-Fi hot spots. Many modern transportation systems, such as planes and subways, also have access to Wi-Fi. The city of Tel-Aviv recently implemented floor traffic lights, allowing phone glued pedestrians to know the state of the cross walk.
