I don't drive in any particularly frugal way, I get as annoyed as anyone else in traffic.
Drivers in 4WD's that refuse to drive up a kerb to alleviate a traffic snarl, kerbs low enough for the average sports car to easily manage, receive a blast from the horn. Old ladies in blue rinse hair driving their new 2 door Mercedes sports car not being able to maneuver into a gap a truck would not have issues with tend to send my face red in frustration.
The other week a guy with next to no driving skills in a Porsche 911 disappeared in my rear vision mirror, no idea how to take corners. More a comment on how hopeless the driver was, not any skill on my part.
And yet I get 3.9L/100km in the Prius I drive.
That is kind of cool.

If the value you are espousing is one that could never get anyone, anywhere, sent to prison, then strictly democratically speaking you are useless.
