When I use lyft now, I'm coming across drivers that only drive for lyft. The tide has definitely shifted against Uber. I'm not really sure there's a way back at this point. The one advantage Uber had was network effect, but in my experience that has diminished. Lyfts come just as fast as Ubers now because they have enough drivers on the road to support the response time. I'll never go back to Uber.
Odd. I'm in the Bay Area and have taken many Lyft's lately both in the south bay and also the peninsula. Usually the drivers I get drive for both even up to this point. Could just be regional, not really sure? I feel like even with Uber's issues many drivers who do ride-sharing as a "job" won't want to just drop Uber as it may mean losing out on income (not sure if they can make up the loss with driving more for Lyft…
I'd say they would be one of the last places to transition.
