I've been posting one "tip" every weekend on facebook to see what kind of responses I get, as a sort of research experiment for how normal people might react in an Efficient Driving Class. So far, it's been the typical opposite, knee-jerk reactions. "I'll never slow down! I wear out WOT sensors as fast as brake pads!" Har har har.
Today, though, I finally got a nibble; "What is your opinion of rear spoilers?"
Another friend from my highschool days asked "What would you suggest to get better mileage in my Cube?"
