RE: 55 mph Speed Limit?
I am sure it is different for each car model but I read where 60 MPH is the ideal speed in gneral and anything over that the aerodynamics several reduces the MPG.
I had a chance to drive in one of the fast areas in the contry on a trip. On I-10 in West texas, where you can drive 4 hours at 80 MPH and still see nothing but hills and dirt.
