So... short version; I think I'm getting slightly carsick from the brake regen, and curious if anyone else is experiencing similar?

Longer:
I've been driving my whole life, mostly sportier (but cheap) cars mixed with station wagons for function, plenty of backroads and twisties, and have never gotten nauseous while driving (though often as a passenger of other people driving).

With the SE, I keep finding that I'm getting slightly carsick from my normal driving routines even when I'm not pushing it at all, and I'm guessing that it's the disconnect of braking without pressing the brake pedal. Brains being funny things and all, I think that my body is used to gas = go, brake = stop, and the disconnect of letting up the gas and my body experiencing braking is what's causing some car sickness.

Anyone else? Just me?

Relatedly, in Low Regen, does the brake pedal kick in the high regen and reclaim that energy, or do I just lose the full benefits of regen braking?

Sorry it's making you motion sick! Hopefully your brain will adjust with time. Regarding low regen mode and manually pressing the brake pedal - the brake pedal does not contribute to recharge. So if you are on low regen, you are reclaiming less energy compared to high regen.
 
Firstly, no, in Low you don't lose all the benefits of regen, there is still regen, just less, hence the name Low. If you find this better suits your driving style - and tummy! - then just use Low and enjoy driving.

So, first EV and/or first EV with one pedal driving? In an ICE car, if you want to coast or use some engine braking, you come straight off the accelerator, and then when you want to accelerate again, you come back on the accelerator - not much finesse needed. In an EV like the SE, you want to come off the accelerator gently - at least right at the part where you're about to take your foot off. Similarly when you get back on the accelerator - assuming you are just cruising along in traffic. Getting off and/or on the accelerator sharply can create the effect you describe - due to the immediate switch to high regen or immediate torque delivery respectively.

It's not a criticism at all - my wife is still similarly adjusting as she didn't like the Tesla and didn't drive it much, and I certainly wouldn't criticize her! It's just a new skill/quirk to get used to - I found it becomes second nature pretty quickly...
 
For those with only two pedal experience, it's slightly more difficult to transition to one pedal driving. I prefer high brake regen and lightly apply some pressure to the throttle pedal to reduce the regen rate until a full stop is required (let go of the throttle entirely).

Low regen is closer to engine braking on three pedal driving.
 
I agree with @teslarati97. I really don't like driving autos because there is very limited, if any engine braking but with one pedal driving, you get the feeling of a manual when you let off the gas. It is especially more pronounced when you let off the gas pedal in higher rpms and the ECU stops the injectors and the engine turns into an air pump.

With spirited driving, I love the one pedal driving because it helps rotate the car in turns.

I actually prefer to drive in Green mode because both acceleration and deceleration (on high regen) feel smoother and more natural to me. I suspect it would reduce the carsick feeling for you.

You've been driving your SE only since June 28th, right? Nearly all astronauts require time to get used to life in zero-G. I'd guess you'll overcome your regen-regurgitation impulse with time. Even in full-regen mode, you have full control over the regen braking with judicious positioning of the accelerator pedal, so you should be able to minimize the discomfort caused by slowing down without using the brake pedal.

Totally agree. One of my many Mini's had the dual-clutch auto, and I did not like it. I had to paddle-downshift to avoid speeding going down hills. I am totally fine with high regen. It took me about three blocks to get used to it.
 
I'm with the OP, heavier Regen leads to carsickness. I lowest possible setting and turn off cruise control: both while descending and when on slower roads when the lurching do to autobraking is pronounced.

When I'm a passenger, I have the driver turn it off entirely.

Just repeating myself from earlier threads, but I agree.

I also wonder whether how you actually press on the accelerator pedal makes a difference to folks' learning curves. I keep my heel on the floor and rotate my ankle, which to me seems the easiest way to finely modulate things. OTOH, if you're somebody who drives an ICE vehicle by moving their whole leg, learning how to smoothly drive an EV using only one pedal may be more challenging.
 
I’ll add my experience here, coming from driving manual ICE cars pretty much exclusively before the Mini.

I was also getting some motion sickness at first and found it difficult to drive the car smoothly, especially in Mid or Sport setting. I used BimmerCode to make the default mode Green, which has a much more natural throttle feel to me. Using the Green mode and learning the “bite” point of the regen (sort of like you would a clutch) has eliminated the motion sickness I felt.

Nice, I'm also fresh off a manual ICE with a top mounted pedal (which someone else mentioned) which I drove like hell, so it's not simply a matter of the braking being abrupt, there's something that hits my body fundamentally differently with the one-pedal stuff.

I drive it in sport, maybe I'll try Green though and see if I can train myself into the one-pedal for a week or two then go back to sport.
Glad to hear I'm not alone though, thanks all for sharing your experiences.

What you can do ? Or what I can do to make my wife use a car .For six years owning I3 my wife didn’t drive that EV once the same story with SE she just don’t want drive a car .She is excellent driver with experience in Europe and USA for 40 years and Manhattan don’t scare her. I give up and don’t try to put her in SE she is always a passenger in those cars biting me up once I hit accelerator. She loves her Subaru.
