THE Bike
Imagine one bike, fitted with a GoPro (or other camera) and GPS tracker. It is given to a random person who may use it. When he or she is done using it, it must be given to a next person to use. Then when he or she is done the same repeats. This continues, night and day. What will happen to the bike? Where will it go? Who will use it? All these questions will be answered.
