Only time I’ve noticed it has less effect is when there’s four adults in the car.
OPD, scary moments
It has been discussed that s/w version 2.7 again reduced the regenerative braking with OPD and that is a pity, but I'm experiencing a serious issue with it as well. The regenerative braking with ODP (standard) is unpredictable. Sometimes you get what you would expect and sometimes there is virtually nothing. I have had several situations where I had to unexpectedly use the brakes because regen just did not kick in. Not often, but often enough to be wary of the OPD function now. I can't figure what circumstances make this happen.
Just me?
PS
No, I'm not taking about a full battery or extreme temperatures. Mid drive, one moment is fine, the next is not.

I and others have commented in the fact that it is not consistent any more since 2.7.
Wether there’s a leading car or not seems to be a factor for me, but I might be imagining things.
I hope 2.9 reverses this but every single release since I got the car 2.5 years ago seems to have affected OPD negatively.

I sometimes feel I'm imagining it and then all of sudden I have an "oh sh ..." awakening.Wether there’s a leading car or not seems to be a factor for me, but I might be imagining things.
How do you think does a leading car factor in?
I'm not sure, but it seems fine if there is no leading car, but tries to run into it if there is?
It feels speed related to me
More Regen at higher speeds (that gets feathered in gently so sometimes it takes a second)
Regen trails off to zero as speed goes to zero
I don't think there's anything else going on other than that feathering in the Regen and varying it by speed

No issues here, but let's collect more data- I'm with a no-packages, SMSR car.
At highway speeds it seems that lifting off the accelerator pedal leads into more regen when there's a leading car compared to when there isn't one. It's less obvious at lower speeds.I sometimes feel I'm imagining it and then all of sudden I have an "oh sh ..." awakening.

That was always the case, although they did tweak the curves a bit over the years (really liked the very aggressive regen on original firmware from 2020).It feels speed related to me

My concern is that since 2.7 there's another factor other than just speed that affects how much regen is applied when lifting off, and it's not obvious what that is (presence of leading car might be one of them) but the end result is that it is no longer consistent and I hate this. When approaching a roundabout I lift off the accelerator and the initial coast time (introduced in a previous update) doesn't feel consistently long, as is the amount of regen. I used to be able to eg control stopping at a T junction just by lifting off within a few meters, that isn't possible, I often end up needing to apply some acceleration input if it surprised me with more regen, or apply some brakes if it coasted more than I expected it too. Overall not as great an experience as before.

The only time OPD deceleration amount has changed for me is when there's a loss of traction on one or more tires (bumps, snow, etc).
Otherwise it's completely predictable and consistent. I drive 65+ miles per day and it's a mix of highway, city, traffic, etc.

Yes, I have observed the exact same thing. It happened a couple of times after 2.7 was installed. Then for quite some time everything worked fine, to the point that I started to believe that it was just my imagination.It has been discussed that s/w version 2.7 again reduced the regenerative braking with OPD and that is a pity, but I'm experiencing a serious issue with it as well.

But as it so happens, yesterday I had another occurrence of this problem while making a quick drive to the local pharmacy: Upon approaching a stop sign I lifted my foot off the accelerator. The car started braking but then it almost felt like a jolt of sorts when the braking force backed off after just a split second. (Or maybe it just never fully kick in, and the "jolt" was just a psychological phenomenon, a mismatch between expectation and reality.) In any case, I had to use the brake pedal because OPD alone would have carried me well past the stop sign. I was not driving aggressively at the time, and the OPD braking force was way, way weaker than it would normally be under similar circumstances.
Something is wrong with OPD since 2.7, and I dearly hope that the next update addresses it.
I have the same problem.

To me it is very noticeable.
Since 2.7 my car often coasts for a split second before regenerative breaking kicks in. This only happens at the start of a journey. After a kilometer or so it's back to normal. This has nothing to do with SoC and defenitely started with 2.7. The lag is enough to scare me.
I also noticed this recently, especially when lifting off the pedal at higher road speeds. It seems I've had to apply the brakes more often than I used to. I can't relate this to any particular software upgrade, though.
This may be a safety up-grade that Polestar isn't really willing to admit to. For example, we recently had a Tesla driver who apparently fell asleep while driving and the car came to an immediate stop in the middle of a highway. The accident killed the Tesla driver and severely injured other drivers. There was no time for the driver aids to alert the driver before the car just stopped when the driver's foot lifted from the power pedal.
Full regen may not be the best idea at speeds over a specified threshold.

But the lag is not consistent over time . That's a problem.
Stories like this are not boding well for the future of OPD. Already incidents in China are causing authorities there to consider banning OPD.I also noticed this recently, especially when lifting off the pedal at higher road speeds.

Surely the driver has responsibility above and beyond that of OPD, how it reacts, it is still entirely the drivers responsibility based on today, not yesterday. I appreciate that the feature for some, continues to behave differently, but these are all aids, not definitive tools.
I worked for a company who provided sensors for ADAS calibration and certification, at no point in my future, would I ever be comfortable giving up control of a vehicle to autonomy.

Wait until people realize how much variation there is in an ICE powertrain with a slushbox automatic.
Not nearly as much as with the p2 😂Wait until people realize how much variation there is in an ICE powertrain with a slushbox automatic.
