There is one big problem I have with uber: Uber takes PERCENT (20%) of ride value, while it has fixed cost associated with ride. In fact it's a uber clever way to tax (sic!) workers. I believe uber will be disrupted, either by nations (goverment must be ultra blind to allow burden its citizens by foreign corporation paying no corp taxes (EU case) plus having most of the cost in different country (all but US case) or by people themselves.
