Durning this whole thread I never thought aboput the big ones at all. To me a different animal.
I grew up near the Orange Circle in Orange CA.

This one has a Park in the Center. A lot of "small town" movies and TV shows film there.
I always thought of this big one as two individual right turns. There is a different driving thought process when they are this big. You can kind of relax for a moment as you get into it. the small ones require the driver to be much more aware.
