If your car kit is inaccessible, thats a pretty bad situation. If I were wearing dress attire and was miles from home, loss of my car kit (extra shoes, etc) would be a major PITA. As Susan mentioned, if the roadways are impassable, walking might be the only way home. And then there's the fires from broken gas lines, etc, etc. After an instant disaster like a major earthquake, improvisation would be the word of the day.
