"People say New Yorkers can't get along. Not true. I saw two New Yorkers, complete strangers, sharing a cab. One guy took the tires and the radio; the other guy took the engine"

This quote by David Letterman is a humorous take on the stereotype that New Yorkers are not friendly and can not get along. He is recommending that 2 complete strangers, both from New York, were able to work together and share a cab. The joke is that a person of the complete strangers took the tires and the radio, while the other took the engine. This is a funny method of suggesting that the 2 complete strangers were able to comply and share the cab, despite the stereotype that New Yorkers can not get along. This quote is a lighthearted way of revealing that New Yorkers can be friendly and can get along, even if it remains in a funny way. It is a suggestion that stereotypes must not be taken too seriously which individuals must not be evaluated based upon their place.
