Movie Incongruities/Lucky Coincidences

[Yahtzee]

Crash probably deserves a mention in a thread about movie coincidences. The two that come to mind for me are:

-Matt Dillon being on the scene of Thandie Newton's car accident after molesting her a few days earlier
-The whole subplot with the blanks in the shop owner's gun, especially if the daughter picked the blanks by accident. (I'm not sure if she did or not).

I guess coincidences can be used for good in a movie, but these two took away from the film for me.
