Hope this is the right secton for this.
Im not shure about other freeways in other areas but my mostly traveld freeway (696 for the Michigan guys) is verry hilly not like san fransisco hilly but evey mile thers a bridge and the freeway dips under maby about 10" food and raised over, and as im driveing up and down i can watch my MPG on the
SG go up and down about 10mpg.
Is this just like a forced pulse and glide? How should I attack this, or should i just drive like normal in this situation.
