Things I've been told by recent Lyft drivers:
* Uber and Lyft "take the same percentage", but Lyft charges more so they get more.
* Uber cheats on mileage, holding out until an attorney general was called in.
* If your ride estimate was e.g. $31, but actually was worth $22, Lyft charges you $22; Uber charges you $31, but pays the drive for a ride of $22, pocketing the difference.
* Uber often charges you surge price but doesn't pay out as a surge. Which, I note, rather defeats half the alleged point of surge pricing (luring more drivers onto the road.)
* Lyft surges based on demand, Uber often surges by the clock.
* Lots of drivers are switching to Lyft.
* Edit to add: Lyft is a lot easier for the drivers to contact and talk to when there's a problem, and more responsive.
Certainly I've been seeing a lot more Lyft availability in Boston than I did a few years ago.
Edit to add: comment below got me wondering about relative pay. A few sources:http://www.ehow.com/info_8522975_much-average-cab-driver-make.htmlhttp://oureverydaylife.com/much-average-cab-driver-make-9448.htmlhttp://work.chron.com/much-fare-taxi-drivers-keep-22871.html
In 2012-2013, taxi drivers were reporting $12/hour on average. This Vox article https://www.vox.com/2014/12/17/7402311/lyft-driver-pay
suggests Lyft in 2014 was similar, but that drivers were enthusiastic about the flexibility.
The Chron.com link suggests taxi companies take a 1/3 cut, and that the drivers may have to pay for gas and vehicle use out of what's left, too.
