Stop stop stop just push the button....or don't push it everyone switch to decaf and go 4 wheeling...

well, the classic alternate method to meet EPA CAFE mileage goals is to go with smaller engines and fewer cylinders.
eg, 1.5L 3 cylinder EcoBoost in the bronco sport.
the next generation will probably be a 1.0L 2 cylinder
i'll take ASS over smaller engine

Who cares. Start stop is a total non issue.
Seriously, I'm the type of person who hates ABS and traction control, and I still couldn't care less about start stop.
At this point it's just bitching for the sake of bitching.

How about making it a “simple matter” of pushing a button if you want the Auto Start/Stop to work? Why default to it being on? Why no default to it being off and letting folks like you turn it on?

In reality less power does not = better economy, it is the opposite: more power, almost always gained through thermodynamic efficiency gains, = better fuel economy. Undersizing engines hurts fuel economy almost as much as oversizing them.
Modern cars are fuel efficient enough. Carbon dioxide is not a pollutant and thus no business of the EPA. See how different premises nullifies your choices?
ASS is an policy based on premises rejected (at least currently) - it is a solution to a problem that does not exist. Now, we need the manufacturers to respond appropriately to the consumers...

I would challenge anyone to prove ass increases their fuel mileage a measurable amount.
If you can, then will that minute savings pay for a new starter that will inevitably need replacing? And what about wear and tear on the flywheel?
Yes I went there. People dislike ASS for different reasons. Some of us simply because it’s more ill conceived governmental overreach that doesn’t really help anyone.

start stop was never about economy, even though it does help. it’s about emissions. after 6 seconds of idling your vehicle, you’re just wasting fuel and spitting emissions out without reason.
And what people don't realize is its not about saving YOU money, and the emissions saved by one car being off at a light is nothing. The few moments your car spends not running is peanuts. It's about those few moments multiplied by millions of cars.

While I dislike the feature, at least the new city MPG will honest. It should be 16-17mpg.
EPA doesn't mandate the start/stop feature... whatever is default when the car starts is part of the MPG efficiency calculations so that's why carmakers default it to on. Hyundai/Kia electric cars default to very annoying regen settings and many owners ask why they can't remember the setting instead of resetting every time the vehicle turns back on.
With that said.. dump start/stop but make the window sticker MPG honest.

Edmund’s looked into that a while back and tested 3 ICE cars (not hybrids) that had AS/S on their test loop and saw ~10% fuel savings on their urban drive cycle in Orange county CA. Engineers they talked to also said the savings are typically 3-10%, which depends on how much time you drive on highway etc.
AAA also did a study of AS/S on three cars and drove EPA’s Urban test cycle and saw 7% savings with AS/S feature
Oak Ridge Nat’l Labs at Univ. Tennessee published an SAE International paper after running tests on the Federal city fuel economy test cycle and the EPA NYC test cycle and saw fuel economy savings of over 7% snd over 25% respectively.
So it has been proven to save fuel, and it reduces emissions, tho how much savings depends on the vehicle and driving conditions. Also as @Ducati1098 pointed out, Ford did reengineer parts for AS/S, and i know durability test procedures were revised for it.
Still, the fact also remains that a lot of people just don’t like it and don’t like that it is always enabled by default.

Well damn if I’m not curious if it would save me anything. But I am way below average in the amount of city driving I do. I sometimes have to remind myself how blessed we are to live in a rural area and we are not the norm.
Yes, you do, through higher prices at the pump. Wasting fuel increases demand, which drives up the price for everyone. Speeding does the same, your vehicle, regardless of what it is, gets better mileage at lower speeds (yes, to a point), so using more fuel drives up demand, which drives up the price at the pump. It's a pretty simple, straightfoward formula. Do I expect anyone to change their driving habits over that statement? No. But it's a simple truth.
As a powertrain engineer, you're not entirely accurate. Smaller engines with proper gearing do NOT necessarily see reduced fuel economy. Properly implemented they do just fine - and by that I mean vehicle weight is also taken into account. Are they hot rods that will pull hole shots and run 12 second quarter miles? No. But they get better mileage.
And since when is carbon dioxide not a pollutant? Greenhouse gases ARE pollutants, and we have drastically, as a human race, driven up the amount of carbon dioxide in the atmosphere. This has been proven through research. Where you're coming up with the idea that it isn't is confusing. Science has proven this stuff, over and over.
I get it, I don't really like nanny stuff on my vehicles either. I miss the days when everything had an option of a big V8 under the hood. But those days were a BIG part of why we are where we are now.
