It was only a matter of time before San Francisco International Airport allowed direct visits from app-based ridesharing services besides Sidecar, and those floodgates have officially opened. Both Lyft and Uber (specifically, UberX and UberXL) now have the all-clear to stop at SFO's terminals. If you need a ride to your hotel, you no longer have to pay for an expensive taxi or else brave the mass transit system. It's difficult to know how this increased competition will work in practice, but a successful rollout could get other airports following suit.
