Lyft Line was built from the start to make daily ridesharing more affordable, but it really comes into its own if you can use a commuter benefits card. It lets you use pre-tax dollars to pay for a ride, cutting up to 35 percent of the price. It's a good thing, then, that you no longer have to worry about where those cards are available -- Lyft has expanded the use of commuter benefits to all 18 US cities where Line operates. Provided your employer offers the cards in the first place, you now have a low-cost way to commute to work without taking a bus or train.
