> Thus a man's home is, for most purposes, a place where he expects privacy, but objects, activities, or statements that he exposes to the "plain view" of outsiders are not "protected" because no intention to keep them to himself has been exhibited.

And you think this applies to the inside of the woman's car that the article is talking about?

In this reply, no, you're not greatly oversimplifying. In your parent comment, you said that going out in public means no expectation of privacy, and I gave an example of a place in public that had an expectation of privacy, which you've defined as "not in public". I think that if you have to call a place that's available to anyone and not owned by an individual "not public" in order to make your original statement work, then your original statement was oversimplifying.
