New York: Yellow Cab (Instantaneo)
The ‘Yellow Taxicab Co.’ was incorporated in New York on April 4, 1912. Its fares that year started at 50¢/mile (equivalent to $11.44 in 2011 adjusted for inflation).
In New York City a ‘medallion’ is required in order to legally pick up passengers flagging on the street. Taxi driving is considered one of the top 10 most dangerous jobs.
