There seem to be really extreme regional differences with this. Wherever I am, when I take an Uber I usually tip a small amount ($1-$2) and as small talk I ask the driver what ratio of people leave a tip. Here in Western Mass I've gotten answers in the 30-50% area, if I'm right. New Hampshire seems to be similar. But in New York, they tell me it's maybe 1 out of 10.
