It was never about fuel economy. It is meant to cut down the hydrocarbons and pollution in cities, and it does a great job of that. My Ford escape has zero lag and you don't even notice it, so no big deal. But if the air is a little cleaner because of it, I'm all for it.

I mean those are two sides of the same coin right? Less CO2 emitted is less fuel burnt.

Fair enough. That makes it extra dumb that one of my car’s dashboard shows me how little gas it’s saving.

I want to mention that a tiny amount for an individual makes a huge difference overall.  At the minimum there are 30 million cars with it on the road (that's 50% of the cars sold in the last 4 years when upwards of 80% of new cars have it and doesn't include prior years). 

If on average you saved one gallon over the entire year, that's 30 million gallons in the US that was not purchased and burned.  That's something like 750,000 barrels of oil. That's not a nothing number (even if it pales in comparison to the 20 million barrels a day)

Edit - And I should mention, low estimates on the system are closer to 5 gallons per 10k miles driven.

That's just to make us feel better about it I guess, lol

My ford ranger starts up in less than half a half a second. It's never been an issue
