Fuel economy mindfulness: can smoother driving really boost mpg?

[StellaW]

Would a 'fuel economy mindfulness' feature that guides you to smoother throttle, gentler braking, and strategic coasting actually boost mpg, or would it just become background noise in a busy commute?

That could work. If the prompts are clear, you might actually notice mpg gains.
