Right, but why not offer tipping in the app? I think everyone knows that would reduce the friction for tipping. One of Uber's original selling points was convenience -- not having to carry cash around for taxis. Now they've solved their problem, but who cares about the driver, right?
Lyft simply asks you after your trip to rate and tip, all optional.
