The other thing that Uber has offered (in general) is more polite drivers. Likely because of the rating system. Taxi drivers, at least in the US, always acted like you should be grateful they even stopped to let you pay for a ride.
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?
