Uber trials revolutionary new idea: queuing up for a cab

To reduce congestion at airports, TechCrunch reports, Uber is trialing this idea in Portland:

Once riders order their UberX, they make their way to the dedicated pickup zone. The app will briefly give riders information on how the PIN feature works. A six-digit personal identification number is then assigned to the rider, who is instructed to provide it to the first available driver.

Meanwhile, the driver, who has received a pickup opportunity at the airport, heads to the pickup location and will get in a queue, waiting for the next available rider.

I mean… sure. I can see how that works, and the PIN feature means there’s still all the benefits of app rides (cashless, accountable). But isn’t this, essentially, just lining up for a taxi?
