However, getting about in Sao Paulo and other large cities can still be a problem. It is not always possible to rely on taxis when making calls. They are extremely difficult to find at certain hours of the day and in certain sections of the city. Fares are inexpensive and sometimes a table used to adjust fares is posted on the inside of the taxi's rear window. It is not necessary to tip.
Radio taxis are more expensive but convenient and reliable.
Rental cars are common, especially at airports. They can be costly compared with other forms of transportation. Local time in Brazil is two hours ahead of Eastern Standard Time. The country observes daylight saving from December to February. When daylight savings is in effect in the United States, Brazilian time is one hour ahead.
