Yes and no, they are in a space which is extremely price competitive. I literally am watching Uber take a dramatic hit in my area right now. Lyft came to town and probably 80% of the drivers solely use them now, driving up the Uber prices.
Now, I only use Lyft - as do most of the people. Plus, most of the Uber drivers are shady here and the people think Ubers a snaky company.
I realize this is ancidotal, but everywhere I go (I travel a lot, switching between Uber and lyft), Lyft seems to be more popular among drivers and riders. They simply don't use it because of price/market share. However, adjust the price or driver's and the equation changes.
I honestly still don't see them making it out of their situation.
