The two times I used Uber, there was a single flat fee paid with no mention of a tip. The driver and I never discussed payment; it was all handled via the interwebs. Given that one of the perks of Uber is the "no fumbling with the credit card at the end of the ride", it would be rather divergent from the whole experience to be tipping separately. I wouldn't have much of an issue tipping if it were via the same payment mechanism, though. Feels weird not to after years of taking cabs.
