it is general etiquette in rio for one not to slam the door of the taxi when getting out - drivers have been known to become quite animated if one of their doors is abruptly slammed by a departing passenger.

for visitors who are interested in reading about the daily life of a taxi driver in rio de janeiro, the book taxi, a vida e história de um taxista no rio de janeiro (taxi, the life and history of a taxi driver's life in rio de janeiro) by gino santos, would make a great read.
