Yes, this is a plastic illustration of how unpleasant driving a car can be.
But is it representative of the _average_ experience of people who drive cars? I don't think so.
Most people experience traffic jams from time to time. But to most people it'll only be a part of the whole car experience.
If this picture represents your view of most people's car driving experience, then it's only coherent, that you think these people have "a REALLY strange definition of <<freedom>>".
By the way, I don't own a car and I drive at most few hundred km per year (in other people's cars).
