Try Italy, Greece, Spain and Czech Republic to name a few.

I don't like Uber as a company, but I dislike Taxi's in foreign countries a lot more. It is not the foreign part that I dislike, but not knowing the formal and informal rules. What if the meter starts at 5 euros? Is that a normal amount here? What if the meter isn't turned on and the driver insists that I make a deal? Is that normal here? etc. Uber might be more expensive than local taxi's in some places, but at least I know what I get.

I agree, except if you're getting a taxi from the airport, as plenty of drivers will happily add on 10-20€ to your price. I always recommend to visiting friends to shop around for a better price, or to just order online (google: taxi airport vienna and lots of websites will pop-up).

Come to Budapest :)

hint: never get into freelancer taxis.
