Answer:  All are true.

Bulgaria:

Taxis are plentiful in Bulgaria and can be hailed on the street or hired by phone. For security purposes, it is best to call ahead to arrange for a taxi; industry regulations are murky, and you may encounter unlicensed, disreputable taxi drivers looking for fares on the street.

Uber and Lyft do not operate in Bulgaria.

Ride-share services are in operation around China's major cities.

Croatia:

Uber operates to nearby islands Zagreb, Rijeka, and along the coast around Split. The service pairs passengers with available cars, with secure credit card payment within the app.

UberBOAT launched in 2017, offering private boat transfers between coastal cities like Split, Hvar, and Dubrovnik, and to nearby islands.

Ireland:

Uber operates in Dublin, but only by connecting passengers with taxis, rather than to a private car. Nationwide, ride sharing is deemed too disruptive to the local taxi industry.
