Need a ride after a long night? Lyft is a cool app that connects you with drivers who ride in cars with big pink moustaches on the front (so you know they're legit.) These drivers are just everyday people who have registered with Lyft and have gone through background checks in order to, essentially, be your taxi driver. They'll pick you up in their personal car once you set your pickup location, and you can pay them from the app.
