Is Your EV Making You Carsick?

The three bullets opening that InsideEVs article:
- The lack of noise combined with EV's strong surge of acceleration can accentuate car sickness symptoms.
- One study found a direct correlation between strong regenerative braking and passengers feeling sick.
- Adding acceleration noise, vibration and visual cues could help alleviate the issue for some people.
My contrary comments:
- The lack of noise when I accelerate my MINI Cooper SE seems like magic to me!
- What enables passengers to distinguish regen braking from friction braking?
- Fake engine sounds make me almost as sick as the Kars for Kids ads do.

The difference between brake regen and friction brake (95%+ SoC) is more pronounced when you are on a downhill slope. Brake regen kinds of absorbs your body weight and friction brake feels like you are being pulled back.
Can't say much for other EVs but apparently the F56 BEV does not make people carsick! U25 is certainly smoother with the Gen5 no permanent magnet stators/rotors, but maybe..too smooth?

Doesn't the driver control how pronounced either type of braking is?
As far as carsickness goes, my wife is sick of my driving. She doesn't like my short bursts of acceleration when driving our SE in town. Now I'm almost always the passenger when there is one.

Braking, yes for both light and strong brake regen modes.
So if you are referring to the brake regen after your short bursts of acceleration..then I guess you could blend in some throttle during one-pedal driving.

This is my thought too.
You need to drive with purpose to offer a smooth ride to your passengers. I drive totally differently when i'm with my family vs when i'm by myself. Not just from a safety thing, but from the fact that I don't want them to all get car sick. This is not taught in driver's ed these days. But I remember my father explicitly putting time in on this topic to be a 'chauffer' to your passengers and keep them happy.
The car is going to operate in the manner in which it's operated in. Drive smooth like a sine curve, happy riders. Drive like a digital sine curve, and your choppy on/off behavior will catch up to you in the forms of complaints and vomit

When I first got my SE the high regenerative braking seemed very abrupt. As I got used to it, however, I stopped noticing it. My partner didn't like it either, but now she drives an F-150 Lightning and is just as used to regenerative breaking as I am. Even my dogs, who initially needed the low setting, are totally adjusted to the high setting now.

I feel this way only when others are driving. It’s related entirely to regen. It’s a weird feeling on the gut. Lowest regen settings are better.
I also have a hearing disorder and the high pitched whine is deeply uncomfortable. Had to give up the EVs entirely due to that.

As far carsickness I never feel this kind of sensation or my wife also .In 9 years BMW I 3 /SE and my wife in 9 years never was a driver in my EVs which I’m very happy about it .Sometimes when accelerating to fast she is smashing my arm with fist to slow me down that what I call carsickness on my passenger side of my better half .People who feel carsickness should switch to a car on picture with couches inside for comfort ride and a noise of V8 and smell of a gasoline .

This, plus I have a theory that those who have always driven large "appliance" vehicles with automatics have never acquired much skill at modulating their ankle position. Lacking the feedback that, e.g., the SE provides, why would you?

My wife gets migraines from specific frequencies. She can't ride in my SE; otherwise, she gets one. I tried changing the wav file from the pedestrian warning and turning it off completely, to no avail. She's fine w her Audi e-tron. She says it's the whine of the motor.

Sorry to hear. We've owned that car too and it still caused my particular issues to flare up. I've had a Lexus LS for the past 2.5 years and that's worked out wonderfully. We were near a BMW earlier in the week and decided to give the i7 a spin, since it's the new king of comfort EVs. Great car on the whole. I did have trouble modulating the liftoff regen in the comfort mode, which affected my passenger.

My dad imparted very similar advice. You've got to find the smoothest inputs and paths for passengers to feel comfortable. Put on your chauffeur cap and pretend the Queen of England is sipping tea in the back seat

Just go under a car and disconnect that speaker just remove one of a terminals and put a tape on it .and in insurance issue once is disconnected you are in trouble.

As I don’t know how many years you drive gasoline cars and you not complain and you can afford I 7 as one of the best EV I don’t understand what is an issue if EV is not your think go ahead with gas cars ahead ! I wish I can drive I 7

Cut a wires to pedestrians speaker on SE and if you don’t want to hear anything from a silent SE play Black Subath or Beatles loudly another alternative is walking silently not using silent EVs

You can turn it off in bimmercode. It's not the pedestrian warning, though. It's the sound of the motor.

So clearly the solution is to replace the motor with something more powerful and increase the gearing, thus being able to achieve legal speeds at lower, presumably quieter, rpm (and Autobahn speeds with earplugs firmly in place).
