Excited about this. I know a lot of people in climates with ice have been wanting this back.Tesla to Revive Low Regen Mode in Upcoming Update

In blended braking systems, the brake pedal uses regen to stop the car until requested deceleration exceeds regen capacity, at which point it blends in friction brakes. Most other hybrids and EVs have brake pedals that operate this way.
No difference in terms of efficiency, just allows for the benefits regen without being forced into one pedal driving. That way you can have throttle liftoff coasting instead of being forced to regen, which some say maximizing coasting is best for efficiency versus only accelerating and regenning.
And of course some may prefer the familiarity of two pedal driving vs one pedal.

Thanks for responding to that for me! I'll add that regen can incur losses of up to 30% (two trips through the motor, inverter and battery) so inadvertent regen such as over-using the "rubber-band" effect or just lifting off the accelerator momentarily to adjust one's foot is not ideal for top efficiency. With a steady foot however there should not be any difference ... in theory.
Due to the lack of integrated braking capability Tesla had to come up with a way of discouraging the driver from using the foot brake and one-pedal is that solution, essentially free as it's all done in software. But it seems it's not ideal for every situation. I would have thought integrated braking will eventually appear as consumers will expect the same options they get on other EVs.
Low regen....I want STRONGER regen!

Hopefully this can be set/remembered per driver profile. Wife is probably going to want it on Low, but she won't be driving it much.

Yup, it's back with update 2023.12.8. Info from notateslaap.

Would be great if "choose the amount" would mean we can also augment the maximum regen. It's too low for my taste.

I don't understand what this update actually adds. I've always been able to change between high and low regen. What's different here?

The option is missing on newer cars since like 2021 ish I believe

I have an August, 2021 built MYP and after downloading 2023.12.9 last night, it didn’t get regen adjustment, just “Minor fixes”.
It’s not a big deal since I’ve been able to adjust regen using S3XY buttons to a much greater degree, but I do wonder which older cars are getting regen adjustment. I thought older cars than mine had regen adjustment to begin with, so maybe just early to mid 2021 cars got it with 12.8/12.9?

On the other hand, I might get it back! (Not that I will use it but I get pissed when features on my car just disappear and it makes a great setting for the valet parking key since you don't have to be assured that the car jockey knows about one-pedal driving.)
