Taxi’s are very cheap in Rome the only problem being you can’t hail a taxi and must either phone for one or go to a taxi stand. I use Uber in other parts of Italy but not Rome. One of my strategies is to rent a car from a small city to avoid the higher rates for renting cars at airports, train stations and large tourist areas and taking a Uber ride to and from the small cities, worth the savings and hassle of the driving chaos of the large cities. I also did this in Beaune, France last month, paying only €42 per day for a great car.

Never seen these signs but will look for them on my trip through Termini Station in a few days and report back.
