This Guy Can Get 59 MPG in a Plain Old Accord. Beat That, Punk.

I wouldn't want to drive the way he drives, but I certainly agree with the idea of being efficient as possible.

is he throwing it in neutral?

I don't think driving like this is reasonable in most circumstances (though I did used to make 90 mph turns in my S2000). But he makes a good point about the FCD (fuel consumption display). If I had one of those in my car, I would definitely use it to discover where I'm burning the most fuel and try to adjust my driving accordingly.

Also - 180.91 mpg from an Insight? What a fucking stud.
