When you think of iconic cities, most people get images of notable landmarks, buildings, and skylines. London has Big Ben, Paris has the Eiffel Tower, New York has the Empire State, LA has those cheap sheet metal letters that spell Hollywood. But there's distinctive mobile landmarks as well — the distinctive cars of cities.
Cars do a lot to define the overal atmosphere of a city. If (I mean when) I find myself waking up in a dumpster in some random city, the cars would be the first big clue as to where I was. Think about distinctive cab fleets — New York was known for its Checkers, then its Crown Vics, Mexico City has its green Beetles, London has black cabs so iconic, new ones are made to echo the look of the old.
