Snapchat shows people where you are and what you're doing

Snapchat's newest feature triggered major privacy fears when it launched last week, but it reveals even more about you than previously thought. Snap Map doesn't just show other users exactly where you are. It also shows them what you're doing. Snapchat is using data like your location, your speed of travel and your phone usage to figure out if you're sleeping, driving, listening to music or even on a flight. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
