You have my upvote for saying it.
I usually don't use taxi in Italy because of the inability of the driver to shut the f*ck up when they are driving. Last time I took one to go back home with my girlfriend and this driver talked to us for half an hour of a conspiracy theory about the Fukushima accident being the result of Japan not allowing some US investment fund to enter their market...
And I have to pay to listen to this shit?
If so that comparison isn't apt. Those apps would summon licensed drivers and the payments would be set by the driver based on the meter or the pre-arranged price. Like a card machine.
It seems to me, that if Uber operated inside the parameters of the law they would not be so profitable. That is really the point.
