I do agree, it “should” trigger brake lights. But it doesn’t.

I actually like that mode (2PD whisper with L) especially with the GTPE softer suspension setting.

But I wouldn’t use it if someone is tailgating. Just know the risks.
I turned 1pd on as I was leaving the dealer’s lot and haven’t turned it off since. It was my first experience with 1pd (first EV), but there is more than 1 way to do things. Nothing wrong with using L mode for this.

“Almost” nothing wrong. The brake light thing. Thus the pages of discussion. ?

New 2023 GTPE owner, coming from a 2021 Prem AWD. @Mach1E your comment about 2PD whisper with L - does that "soften" the magneride suspension? Haven't tried it, as I've always enjoyed Unbridled and 1PD driving.

Yes.

The only way to change mag ride settings is through drive mode. Whisper the softest, then engage and unbridle the firmest.

Unfortunately it changes steering feel and throttle response at the same time.

I don’t agree with this part Tim. I don’t think they realized anyone would want to permanently keep the car in 2pd with L mode on as well. I think the original idea was to give the 2 pd driver an extra tool for downhill grades that they wouldn’t otherwise have. As usual, people are inventive..
I think we're saying the same thing. That's what I meant by stuck in an ICE mindset. They were only thinking of L gear for the typical ICE use of it (downhill engine breaking). They were too shortsighted to consider that people might use it for a high regen level overall, which is further evidenced by it being called L gear rather than simply calling it "High Regen" or something. Which is what they should have done, as being able to independently dial up high regen (without being saddled with tougher steering and less pedal play that accompanies Unbridled mode) is an obvious plus some would want.

I'm frankly surprised Ford was that shortsighted. They knew people would want it, since they made the 3 different drive modes have different regen levels. Doesn't take much foresight to think "Ya know, maybe people might like high regen all the time in 2PD but without the tougher steering and less pedal range that comes with Unbridled". All they have to do is unbundle those 3 things and make then individully selectable. Kinda disaappointed they haven't done that via OTA yet.

I think this is the best TL;DR of the entire discussion.

I was a longtime driver of manual shift cars, and while I used engine braking extensively, I always gave a glance to my rearview mirror before engaging in heavy engine braking. This is good advice for anyone using "L" mode as well (and just in general - drivers should check their mirrors frequently but I bet many don't).

I drive in Unbridled mode and the brake lights only come on under certain circumstances. You need to be developing enough of a rate of deceleration in order to activate the brake lights (generally you won’t without adding a little brake). Often the brake lights will come on and stay on under regenerative braking if the brakes are lightly tapped at the beginning of the event. And, of course, the brake lights always illuminate if the brake pedal is depressed. ?‍♂?
I was driving in the unbridled mode the other day and took it up to a pretty good amount of speed and from what I felt it seems like in that mode there’s no regeneration, there’s no slowing down. It caught me off guard because I almost couldn’t stop in time for the light. I’m so used to one pedal in the engage or the whisper mode where like 200 yards from the stoplight I left off the pedal and stops almost perfectly each time. Is there regeneration in the unriddle mode because it sure doesn’t feel like it? Whenever that lightning bolt turns green, that means you’re regenerating?

Yes, in Unbridled mode, the car should have a more aggressive rate of regeneration, causing more powertrain drag. ??

Our roads are icy half the year. I have made it a habit to ensure I do not get rear ended if someone can’t stop behind me. Leave a bit of room up front so I can pull forward if needed.

Not exactly the same but certainly close enough except for minor quibbles. The fact is that the way you’re using L mode is not uncommon and is well within the realm of normal safe operations. Plus it's an established driving technique now. Ford should put an L mode brake light on their blackboard for future OTA as a safety enhancement update.

Upon reading the thread I decided to see how the brake lights behave under OPD. I don’t drive in L but D under whisper mode.
To see the brake light behavior I taped a piece of paper on the lift gate hangover, halfway block the high mounted brake light so that when it lights up I can see the light reflection from the driver seat.
the light didn’t light up until I released the accelerator to a certain point, not as soon as I relaxed my right foot. You can try it yourself to see how it works under your favorite drive mode.

Looks like I'm wrong again, but I thought that the deceleration sensor would activate the brake lights if in 1PD or not.
If not, why not?
Mach-E was designed for brake lighs to come on in 1 pedal drive when you ease up on the gas pedal. If not in one pedal drive .brake lighs will not come on until you hit the brake pedal, it is that simple.
