that my average fuel consumption is so high.
Why would you be "pleased" with a bad personal outcome? As far as How Stuff Works, the energy embodied in the fuel used has to be transferred and dissipated through all parts of the engine and drivetrain. So, accelerated wear of clutch, gearbox, differential, brakes etc. Even from the fuel pump to exhaust.
It's a bit like being "pleased" with self-harm. Entirely irrational.
What you _should_ do is take a course in motor mechanics and learn to service and maintain your car. If you learn how a car works you might actually drive it more sympathetically and achieve better fuel consumption and reduced maintenance costs. Which isn't to say not having fun - just using more brains than balls.
Now, if you're going to be dashing in and out of busy traffic, slipping into tight gaps there are also negative outcomes for other drivers (unfortunate enough to be) around you. Considering traffic flow as a fluidic system you're introducing turbulence and will negatively influence other drivers' fuel consumption and average speed. And plain just being an annoying prat. That's where I step in. If you behave like that around me you might suddenly find a large ladder-frame chassis flat bed truck swerve in front of you causing you to perhaps lose the contents of your bladder or colon. You might throw a hissy fit until you see the large, heavily built psycho (albeit with a science/engineering degree) in the truck smiling his psychotic smile at you. That's when anger turns to nervousness turns to outright fear.
