I think Uber drivers try to solicit tips from female passengers far more often than from male passengers. I rarely tip Uber, have taken hundreds of rides, and have never been solicited. (When I do tip on Uber, it is either going to the airport overseas to get rid of spare cash, or if something exceprional happened. I've taken UberX in major snowstorms and in that case happily tip $20. I left a laptop in an Uber and got it returned to me within 5 minutes, I tipped $50.)
