Human: I am going to San Francisco next month.  Can you tell me the history of cable cars?

Assistant: The cable car is a symbol of San Francisco, and it’s actually been a common form of public transportation since 1870.  Before the cable cars, people traveled by horse and cart, ferry, or on foot.  The cable cars were introduced in a large scale in 1872.  They are currently a major tourist attraction, and they remain a popular form of public transit.

Assistant: Cable cars were invented in San Francisco in 1873.  They were the first successful cable cars, and are still in service today.  The cable cars themselves are kind of a strange historical footnote, but the system they created has been hugely successful and has lasted for over a century.
