When I originally got my HCH I liked the idea that I could drive it "normally" and save some fuel money and if there's a fuel crisis I can stretch the efficiency out to reduculous measures.
Personally,
I had intended to cool off my agressive driving habit to a reasonable level but as some others have experienced- I swung radically the other direction.

Even if someone is a leadfoot now, while gas is "only" $2.50/ g :
When gas exceeds $3.50 or $4 / gallon it might be good to have a vehicle which can deliver exceedingly fantastic MPG, rather than one that can not.

I bought my car when gas cost $1.20 / g in case it ever exceeded $2.00.
I'm so glad I didn't get the next runner up which was a shiny red Neon.

Efficient drivers do it better.
