American tourist handed €470 traffic ticket.Florence police fined an American tourist €470 for driving a Ferrari in the city's famed Piazza della Signoria in the historic centre on Monday, Italian media reports.  The 43-year-old man drove into the pedestrian area by going against the traffic on Via dei Gondi before parking his Ferrari in the statue-filled piazza.   The driver of the Swiss-registered sports car had an American driving licence but was not in possession of an international driving permit or official translation as required by law.   The €470 fine, which the tourist paid immediately, took into account parking in a pedestrian zone, driving the wrong way down a one-way street, and driving licence irregularities.   Two months ago an American tourist was fined €500 for driving his rented Fiat Panda onto Florence's landmark Ponte Vecchio bridge which dates to 1345.
