Waze Carpool. I'm not sure if it's available worldwide, but in Israel it's working pretty cool and allows you to collect up to 4 passengers on your way to work and back. It also matches you only passengers +- on your route so you don't become a taxi driver (they adapt to the local regulations around this since Carpool is allowed in Israel, but Uber isn't..)
