hypermile

I'm working on a post disproving of myths about hypermiling. So far I've myths of safety and legality covered but I need more. Post your hypermiling myths below.

My fellow hypermilers how do you get the most mpg? Share your favorite fuel efficiency maximizers here.

Is it illegal to go down a hill in neutral with your engine on? I know in some states it is but in others not? I' drive mostly in New Hampshire and Vermont.
