Here in So. Cal. if you are on the freeway and not going 75-80 MPH, you will be rear ended (unless there is rush hour traffic).

My car runs 2200-2400 RPM at those speeds and provides a nice quiet cruise. If I want to accellerate quickly, I downshift. If mild accelleration is needed, fifth is fine. Don't want to be turning 3000 RPM on the freeway. My engine drives just fine at 2200.

To each his own. Do what suits your driving habits, road conditions and engine setup.
