Society's winners and losers of Uber and Lyft (it's a love/hate relationship)

5 Stars for Convenience... 0 stars for congestion. The Uber and Lyft-led ride industry has made life easier for many: whether it's having a few too many margaritas with dinner, visiting a new city, or needing a ride to the airport. It's also never been harder in one way: traffic. Here's the low-down, based on studies summed up by the WSJ:

• The Pitch: Uber/Lyft pitched themselves as ride-sharing apps (picture 4 strangers in a Prius heading the same direction). Five years ago, Uber founder Travis Kalanick said it would end congestion: "If every car in San Francisco was Ubered there would be no traffic."
• The Reality: Congestion got worse. Most riders hail private cars — an estimated 70%-80% of rides in major metro areas are non-pool. Drivers in NYC and California cruise without passengers ~40% of the time. Though Lyft estimates 500K Americans gave up personal cars thanks to ride-hailing (not ride-sharing).

Negative effects take a back-seat... When you can get contact solution delivered to your door same-day by Amazon, you're probably not thinking about delivery vehicles congesting streets. Similarly, users of ride-hailing services are likely to think more about convenience than traffic or pollution.
