Well, the very reason I have a Lightning is brakes. I met up with a deer that totaled my expedition. This deer popped up outa the ditch, I swerved to the left and went for the brakes. I have replayed this a thousand times in my head, it seemed like an eternity moving my foot from the gas to the brake pedal, and the slow gush of the booster to full brake pressure. All the while screaming in my head, MOOOOVE, Boom!
The braking on these trucks is incredible, But with one pedal deceleration begins the instant you back off the gas, you are slowing dramatically instantly, wish I would have had that instant, I would have missed that deer completely, But then I wouldn't have my Lightning. Thank you Deer!

What in the world are you talking about? This is the most imprecise and ambiguous statement I have ever seen.

1pd drive and the brake pedal BOTH enact regeneration to slow the vehicle, they both do, there is no difference if you do one or the other.
The point of that detailed explanation was to prove that 1pd changes driving characteristics. One of the commentators stated that they were able to overcome them with a driving style modification.

I was simply highlighting that this driver is now creating a new problem, which is that they are going to spend their time and focus trying to out-navigate the drag effects of the re-gen braking with their style adjustment. And in so doing, will reduce the impact of the re-gen.

So bringing it all back together. 1 pd has pros and cons. Pros are increased mileage and a unique driving experience. Cons the truck experiences drag, is less controlled in the snow, and requires a change in thinking/technique while going in reverse and parallel parking.

And if you want to try threading the needle to have the vehicle "feel" normal while using 1pd, you will need to try to make it happen and you will not maximize the benefit of increased mileage.

There is no "out-navigate" the "drag effect". There is no drag effect, 1pd drive is regen, which is slowing the vehicle. Which is exactly the same as if you slow the vehicle without 1pd drive. And truth be told, I DON'T drive in 1pd drive, but even for me the only time spent is remembering to NOT fully release the gas pedal. There is not much to it at all, this isn't heal-toe shifting here.

There is no increased or decreased mileage. 1pd drive or 2pd drive will have the same efficiency. The vehicle speeds up and slows down in exactly the same way.

It is not less controlled in the snow. If you do not know what you are doing and suddenly jump off the accelerator that is not good, just the same as pressing the brakes too hard is not good.

The parallel parking maybe, simply because of the automatic brake hold.

Again, I don't use 1pd drive with any regularity but in no way find it to be "threading the needle" when I do try it, its really quite easy to control. Nor would a slightly less than perfect technique change your mileage, this isn't a gas car engaging the mechanical brakes and then suddenly having to put fuel back into the engine.

Agree, this one takes a bit more practice. I've found the brake hold doesn't kick in as long as you have gentle pressure on the accelerator. The space between the applying power and automatic brake hold is larger in reverse to assist with smoother parallel parking. You actually have to press the accelerator further down to move in reverse making it easier to stay in the coast zone - Well thought out by Ford, but it does take a bit of practice.

I honestly think you might need to read up on the subject we are discussing.

Specifically, the following claims.
1.) There is no drag effect while using 1pd.
2.)The effect is the same as if you were using 2pd [hint: you are conveniently dismissing the free float period before brake application]
3.) There is no increased or decreased mileage, the vehicle speeds up and slows down the same way [All that non-sense about brake coach and energy return is an illusion] [Hint: The vehicle slows down the same way....except it doesn't because in 1pd a computer is tasked with the job, in the other a human.]
4.) It is not less controlled in the snow [Hint: A computer behaves differently than a human being]
5.) The parallel parking and reverse [Hint: There is a subtle but important difference between using a pedal to reverse vs. letting gravity and friction do their thing]

One of the issues I have found with being deeply familiar with these vehicles is that I am able to articulate the pros, as well as the cons of ownership. At the same time, I have found that many owners simply look at the pros and attempt to minimize or ignore the cons, and then wonder why people don't buy the truck or in this case, use the feature.

It's ok that there are drawbacks and that the truck isn't perfect, but don't try to then come back at me without doing the homework and expect me to let it go unnoticed ;D

Have a good one.

So lets address that.

1. There is no DRAG effect using 1pd driving. You can possibly slow down, by regenrative braking, in the exact same way using the brake pedal provides. Yes, if you let off the accelerator you slow down, which is different than in 2pd driving, but that is literally the POINT of 1pd driving so using that as a "difference" shows a lack of understanding of the topic.

2. Yes, there is a coasting if you let off the accelerator in 2pd drive. That is quite obvious and I really hope you don't need that explained to you. We all understand that and are quite beyond that in this discussion. Again, that is the ENTIRE point of 1pd driving. Obviously letting off the accelerator in 2pd driving coasts, no crap. If that is your argument then you really need to catch up to the points here.

3. Yes, the vehicle slows down the same way. I don't understand how you are lost here. If you release the accelerator a set amount regenerative braking slows the vehicle a set amount, in exactly the same way as if you press the brake pedal a set amount. The electrical and mechanical systems work exactly the same, where the driver makes their inputs is what changes, but that does NOT change how the systems work.
The energy coach identifies if you brake MORE than regen can provide, which 1pd drive wont' do automatically but you can do with the brake pedal. In both cases if you wanted to slow down that much you would need to apply the brake pedal to a level that engaged the mechanical brakes. Provided you do not exceed the ability of regen to slow the truck you get exactly the same energy back, and if you exceed the level of regen then you needed to slow down more anyways.

4. Again, the vehicle response to drive inputs. If that input is releasing the accelerator a set amount or pressing the brake pedal a set amount the vehicle responds the same way. There is no one or the other in charge depending on what mode is used, they BOTH use the driver inputs.

5. Where do you get gravity here? Do you only parallel park backing downhill in reverse. Outside of 1pd drive the computer is automatically applying throttle to move the truck, it isn't "coasting", its being driven. That is a computer function designed to mimic an automatic transmission. If that wasn't there the truck would be like a manual vehicle in neutral.

The rest of that is just trying to make an argument by claiming "I'm so smart", if your counterpoint is just to claim you are smarter than everyone and everybody else is just dumb....Bottom line I think you feel you are so far ahead of everyone they can't keep up, in truth you seem to be way behind the conversation, which is causing the issue. I mean, your not grasping that 1pd drive isn't "drag", its regenerative braking, the same regenerative braking that pushing the brake pedal provides. That "gravity" is doing your parallel parking for you? Seriously. Or that how much you release the accelerator is the exact same thing as how much you push the brake pedal, but somehow you think one mode responds to drivers inputs, but the other somehow does not? So maybe stow the condescending garbage and provide real inputs, oh and go learn how 1pd drive works since much of what you said shows little understanding of the system.

You’re losing the plot.

You claimed that there is no material difference between 1 and 2 pedal driving.

Then proved that there is.

The question asked was why are people not using 1pd, the reason you are now giving “regenerative braking” is what I said when I called in “drag”, in order to simply and describe the feeling users experience.

I’m not smarter than anyone, I’m just answering the questions.

With 1 pedal driving, you no longer have the free coast aspect of driving, which makes the driving experience different.

This is the core of the answer.

Stop trying to make this a typical internet back and forth and simply accept the facts, it’s really not that big of a deal.

When you provide facts instead of you yourself just claiming you have, then we can get somewhere. Continuing to claim so just shows how weak your arguments are.

" “regenerative braking” is what I said when I called in “drag”, in order to simply and describe the feeling users experience."

This is trigonometry, put the coloring books away.

I am pretty sure all Teslas to date only do regen from one pedal driving and their brake pedals only activate the friction brakes.

Not sure about other brands, but Rivian also did not have any regen from the brake pedal that I could figure out during a test drive.

Tesla has done regen on the brake pedal only in the last few years - Originally it was only in 1PD but they have evolved the system to include regen on 2PD. Not all Teslas have this. Some Tesla owners say it isn't as good since the brakes don't feel as solid. With Ford, most can't even tell it is doing regen with 2PD on braking.

I think you are correct with Rivian. I believe is all 1PD regen and you can't turn it off. I don't think they have a 2PD like Ford - It is a deal breaker for some.

Porche uses regen on 2PD similar to Ford's 2PD. To my knowledge, they don't offer 1PD.

Chevy started in 2011 with 1PD regen on the Volt and has progressed through a number of iterations including regen paddles on the steering wheel. Current EVs like the Silverado EV give you a choice of 1PD regen or paddles but to my knowledge it isn't used on the brake pedal.

I believe Hyundai only does regen on 1PD (i-Pedal) mode. I'm not sure if it can be turned off, the level can be adjusted.

I quite like the simplicity of 1PD and 2PD from Ford. While it would be nice to have a setting to adjust the regen strength in 1PD, we know we can increase by using Sport mode. 2PD works as it should leaving regen complexities to the technology in the truck with no impact to driver style coming from ICE F150.

1PD or 2PD is simply a preference.

Digging into this some more, there is some confusion about Tesla, because they have something they added in the past couple of years called "Blended Braking", but its actually kind of the reverse - it applies the friction brakes when you let off the accelerator if needed to make sure you always slow down the same predictable amount when regen is not available.

Chevy Bolt (and the old Volt) is reported to have good blended braking from the brake pedal.

There are also many hybrids that only support 2-pedal driving. The Prius hybrid seems to get mixed reviews that the transition from regen to friction brakes is not smooth.

I started off with 1PD and switched it off after it engaged the break on snow and skidded a bit. With 2PD, I'm actually coasting when able, using regen to slow, and the big improvement...not flashing my brake lights every time I take my foot off the gas. not sure if I'll go back when the roads clear.
