I can't see how they can offer a cheaper service once all major companies have decent apps, dynamic pricing etc. At least here decent apps are standard for all major companies on the market (no live tracking or pre payment but at least very good booking and price info up front). Given that a lot of the income for the major taxi companies come from major deals (school rides, elderly, large corporations) that uber won't take, I don't even think they need to adopt all of ubers' practices to compete with them. As a matter of fact I don't think Uber is any cheaper!
