It's about awareness.

The best way to get awareness about 'Eco Driving' is to obtain a bicycle and ride it around for some distance both in town and a little further afield. Then, as in a way that will never be made viscerally apparent to you in a car, you will instinctively understand:

the importance of correct tyre type, condition and pressure
the importance of not carrying unneccessary weight
the effect of wind drag
the importance of not pedalling when stationary!
the importance of smooth, fluid progress and not accelerating or braking without good reason
the importance of changing gears for the optimum motion with least effort
the importance of anticipating traffic flow
consider a tandem??

It amazing what you learn when you provide the motice power instead of 150 BHP under the bonnet.

Simple really, but shows how fossil fuels disconnect us from underlying physical reality. That of which every cyclist is acutely aware.

And once you've obtained a bicycle and ridden it, don't get back into your car except in an emergency.

Great post, especially: "the importance of not pedaling when stationary!"

I walk to work much of the time and am constantly struck by how loud/wasteful/rude cars and people in cars are. When I'm in my own car, of course, none of that applies. :-)
