This type of information should be in each State's driver handbook. My daughter's TDI Jetta gets 37.5MPG when she drives it and 55-57MPG when I drive it. I, too have tried to explain momentum and inertia. To her it is just magic and weird driving.
Keep up the good work and maybe we can make driver education a high priority within an especially outside of our community.
I sure do miss my 75MPG Lupo I had in Germany
