General comments from our recent road trip to FLA from MA for school vacation week along the I-95 corridor.
Total miles- 3,500 Trip average- 35mpg Ave. highway speed- 75mph
The trunk was completly full, + driver and 2 pass.
First tank had 400+ miles of sub freezing nightime driving, against a substantial headwind, and only saw 31.5mpg. Most of the time in FLA I was around 36-37mpg. Several tanks of around 550 miles, and never put in more than 14.5 gallons.
I never saw another HAH during the entire trip, and only 2 Prius anywhere south of New York. At 75mph, I was frequently relagated to the slow lane as all the SUV's and pickups passed me at 80+

. In fact, far fewer cars from up north than SUV's.
Based on at least 4 separate 100+ mile checks, my odometer is about 1% high.
It was good to get out of the cold for awhile, and always good to see the rest of the country. Everybody should get out and take a road trip once in awhile, its a good reality check.
