Nothing wrong with a F150, and if the scenery is nice, maybe drive slow and take it instead of getting all wadded up.
I don't like holding people up, but if its a nice day and no one is behind me, I'll cruise in my Porsche with the windows down and 10-15MPH under the speed limit. Saved me a wreck one night when a deer jumped out of a ditch in front of me, doing 15MPH under the limit I was able to easily brake for it.
