Olympic bids often do help encourage public transit development in the US, however - a great recent example here is the extension of the 7-line subway in NYC, which was originally planned as part of the city's bid for the 2012 Olympics. After the city lost the bid, it was decided to go ahead and build the line anyways as part of another redevelopment project.
