Uber, in Spain, has been banned. The "pissed off", here, are the legitimate taxis, who pay 150,000 euros for a license plus extra insurance and all the rest of it.. Its all a question of economics.
The cheap, unlicensed, taxis are ok, until you get in an accident. Then the problem for the passenger is the insurance. He will have to go against the taxidriver, who is, probably, in gaol and bankrupt, anyway,
