BUT, my overall slowish time was attributable to a significant number of Highway Patrolman out on the road, especially in California. More than I have ever seen here. I rolled up behind one, while going 100 MPH but recognized the silhouette of the Crown Vic from 2/10ths of a mile away and slowed up before he saw me. I paced him @ 80 MPH for easily 50 miles. :\

I did have several instances where the detector saved me from certain citation.

Average speeds (which includes stops… which you guys did not factor in!) on a per-hour basis were:
62.5 (I had a ~10 minute interlude where I stopped for a panic wallet search a few miles from my house!)
73.5

The first half of the trip was into a 40+ MPH headwind. This and my lead foot caused my worst mileage EVER in my car. 42.9 MPG.
