Drivers drive for the product that provides the most income. Outside of the realms of SF (and even within), there are only two types of drivers:
1. Ones who drive for both - this cohort used to prefer Lyft due to tips but the scales have tipped (no pun) due to Uber introducing a whole host of features which Lyft is catching up to. This is easily verifiable by frequenting reddit.com/r/uberdrivers or reddit.com/r/lyft
2. Ones who only drive for Uber because the demand is overwhelming enough to not justify managing two separate accounts.
Anything else you hear is pure anecdote. My source - I am an Uber employee :)
