My understanding is that the brakes will only activate if you're requesting to slow down faster than reduced regen will allow. That means you can still begin slowing down from further out and avoid the brakes activating if you want to. But if you don't do that and expect the braking distance to be the same then with reduced regen you would have had to apply the brake anyway.
Personally I think the braking distance being consistent so as to allow the use of muscle memory is a fair trade for some extra brake wear (which is probably minor since it would only happen at the end of the stop, at lower speed). I don't like having to guess or feel out what my distance will be today and adjust accordingly.
Same, although my "up to date as of" date is correct.
Exactly... or at least that's how I too would expect it to function.
Agreed. But I'm also a proponent of most things being user configurable, which supposedly this will be. Of course Tesla also used to let you turn off regen braking and then they removed that option in later productions.
I'm not so sure about that. On my car I can get some pretty aggressive regen slowing from highway speeds down to spirited exit or transition ramp speeds. Maybe some day we will get to a point where this talk is moot because regen/motor brakes will satisfy all primary and emergency braking requirements and the traditional hydraulic friction brake system can be entirely omitted. Then we'll still be talking about braking curves and software adjustment sensibilities.
Agreed. Lest we forget that over the years things like brake drying and other features have come into play to further normalize braking behavior. Regen brakes and their variability seem to be the most significant backslide to this normalization that I have experienced in recent years. I joked with a friend years ago about how I wish Tesla would just have included a big resistive heater to directly dump regen into when the battery was cold or at high SoC. It would probably be size and weight prohibitive on a car, but diesel-electric locomotives have systems like this to support their motor braking systems.
It's strange. I'm just going to ignore it being wrong on mine as it clearly didn't stop the car from being able to receive an update.

I can't leave. Don't want to wear down my brakes!You need to get out more if that's the most ridiculous thing!
On a serious note, I thought I read that the brake blending only occurred if the battery was near 100% capacity or there was an over-heating potential, so in general the brakes should rarely be used in preference for regenerative braking.
That was my understanding as well. A majority of the time regen is going to work like it always has. The brake blending would only apply at high SOC or if your battery was cold. In those situations, you would be applying brakes anyways.

I think there is some misunderstanding of when/how this works.... it would use the friction brakes to mimic the regen braking only when regen is unavailable (or not fully unavailable). For example, when the battery is 100% charged or it's very cold, there is no or very little regen available (at least in the LR). So in this case when you lift your foot off the accelerator, it will will apply friction brakes so that the deceleration you get is the same as though you had 'normal' regen.
This setting does NOT blend the friction brakes in when you have the usual amount regen available.

So weird that people can't wrap their heads around this. It saves you the trouble of moving your foot over to the brake pedal whenever the car fails to regen in a normal manner. That's it.
It has nothing to do with brake wear, regen ability, or the Illuminati. It just saves you the trouble of having to reaction-brake when regen is inadequate. Period.

Oh well. Maybe someday.

Anyhow, after a 1000 km road trip up and down the mountains of France with 2022.16.1.1. The predictions of energy usage on Navigation seem to be very accurate...without giving any information about how they calculated it...for example on one leg of my trip, the energy prediction for the return was much lower than going....and it was uphill all the way and downhill on the way back
I see you are located in Los Angeles. Have you ever driven the care in single digit Fahrenheit weather with a battery that is cold soaked? If you plan on stopping you will be using the friction brakes.
Also, for those of where roads are salted I'm actually quite happy to exercise pads and the calipers so as to minimize the chance of things sticking and causing uneven wear.
My expectation is that under most driving conditions the feature won't actually be activated, but there is no way to know until it is released.

FWIW: the Apply Brakes when regenerative braking is limited option is now showing up. I have no idea when it appeared because I haven't been looking for it. I'm currently on 2022.20.7. It wasn't there when I got 2022.16.1.

Can confirm - my April 2021 MYLR just got this as well. I'm also on 2022.20.7
Oh sh... I just found that on my 2022.20.7 too. It wasn't there when I check it on 2022.16.3 or on 2022.20.6. I had been looking since it was first mentioned.

[Notateslaapp] According to @greentheonly, this feature is only available on limited Model 3s and Model Ys with specfic hardware.
What specific hardware so far?
Definitely looking forward to this feature.

Option is available on my November 2021 build 2022 M3P. Not that it would be used in the heat of summer.
