I feel you did the right thing, there just things that are so far out of our control.  These moments are our best teaching moment, I learned very quickly that what has happened to you can happen to anyone at anytime.  For the Bride to very angry at you is probably the only way she deals to deal with her anger in that present moment.  I would like to think after the wedding and things have calmed she will realize you are not in control of how others drive, you didn't...
