Saudi Arabia – one which may one day feature robotdinosaurs and its own miniature moon – currently exists as just a line on a map.And that’s all it is supposed to be: The Line is the first part of NEOM, a futuristic $500-billion, clean-energy powered city of the future that consists of several “city modules” arranged along one single 106-mile long road in the middle of the desert.While it’s based around a single long road, The Line isn’t for car owners.
