I drove Lyft and technically Uber for like a month last year and out of day 20 rides I probably got like 1 tip.
I always try to tip if I'm an Uber rider, just because I know it' snice to the Uber guy/gal and sometimes they would really need it.
One time I tipped a guy and the next day I felt like it wasn't enough and I tipped more.
