App-based carpooling options like Lyft Line and UberPool are useful if you'd rather not drive to work yourself... but what if you do drive, and want to make a little money on the side? That's where Lyft's newest offering, Driver Destination, could come into play. The tier lets you only accept Lyft Line requests from people who are headed the same way, with few if any detours; your trip home shouldn't turn into an epic journey just because you picked up someone who lives off the beaten path. If you're willing to make it a staple of your commute, Lyft reckons that you could make as much as $400 more per month. That's not spectacular, but it's enough to pay for large bills or a lavish night out.
