The Brooklyn Dodgers name stems from a nickname given in the 1890s to people who, in a matter of life and death, had to evade railcars speeding down the streets. They were known as trolley dodgers. Trolleys were new inventions, which led to two issues. First, cities lacked the safety infrastructure which protects pedestrians today (e.g. well-delineated pedestrian paths which minimize intersection with traffic to deliberately designed, high-visibility crossings). Second, trolleys were much faster than the alternatives with which people were accustomed (horse carriages), and so folks were much less prepared to deal with them safely.
