Coast Mode/Regen Brakes Make Me Car Sick

[RivianDad2]

So…. I’ve had the car four four days now and am having issues getting car sick when I drive it (with the exception of spending hours going through canyons in a couple of occasions, it’s never been an issue for me). I’ve tried all of the suggested suspension mode and ride height combos, but I think it’s just the regenerative brakes.

Does anyone know if/when Rivian will update to allow the regenerative brakes to be turned off to allow for smoother coasting?

If you’re around San Diego you can go for a ride with me and we can see if you get sick, or if it’s just your driving.

Nope. Throttle pedal modulation is your friend. Once you get the hang of treating it like both accel and decel, you’re golden.

Some people tend to fight it because that’s how their ICE vehicles have worked … it’s not a winning strategy.

Don’t try to coast. I know hard to do after all these years. Think of as a speed pedal and never fully let off until at a complete stop. It took me about a week . I love full regen now and can drive really smooth.

My kid gets sick if I let it do full regen. Meaning, hold the pedal until the very last second and then remove your foot completely. I've gotten used to gradually slowing down by slowly releasing the pedal which feels a lot more like "coasting" in an ICE vehicle.
Driving it like this is probably also better for tire wear.

Maybe try the Gauges app on an iPhone and record G-Forces on a drive that makes you nauseous. Try to be smooth when accelerating and using regenerative braking. That means small inputs and not letting off the accelerator completely and suddenly to stop. Smooth is the goal.

I am smoother at driving with one pedal than I am ICE. It's not the system.

Same. It surprised me that I was able to drive so smoothly after the first stop on the test drive.

@RivianDad2
Some options to test with increased coasting (which I mean coast like feeling with your foot still on the pedal)

A. Snow mode- allows for low Regen
B. When ACC is on and you accelerate above the setpoint it'll let you coast down to the setpoint better than usual. Think passing on a single lane
C. Fill up to 100%, this will disable full Regen temporarily

These are only meant as workarounds to see if it is the regen causing the problem

My son has severe motion sickness so we were really worried about the regen. I’ve had the R1S since August and have graduated to high regen and no one can even tell there is regen happening. My wife pointed out the other day, how do you get it to stop so smoothly. Give it some time and it will become 2nd nature. Now I miss regen when driving any ICE car.

My wife and I were like this on our first EV (Tesla) our body just wasn’t used to the acceleration and regeneration. Took a few weeks to a month but both of us got used to it. With the Rivian I didn’t have an issue. With my EQE loaner I had a small issue. Just wasn’t used the way it handled regen, but after a few days got used to that too. I wouldn’t worry.

Literally the opposite with me... I've never been nauseous in a car until riding in my wife's new PHEV the other day on windy roads to our cabin. We've done them so many times in the Rivian, no problem with one-pedal. The PHEV required more brake use, I had to lower a window...

Go get yourself a beater car with a clutch and grind through those gears for a while. Once you get the hang of engine braking and clutch transition in that, you'll understand how to one-pedal drive. Then pass on the beater to your kid to both learn like you and appreciate a clutchless transmission.

I love the regen feature. It is so much smoother than a vehicle that coasts and that you have to use a brake pedal to slow down. It's hard to drive my wife's car after getting used to the R1S.

I totally get what you mean. A friend of mine got a model Y and a few of us went on a drive across Los Angeles. He was constantly on and off the throttle. By the end of the ride, passengers were ill. They have since driven with me in the R1S. No complaints. Don't give up. Concentrate on releasing the pedal as smoothly as you apply it. Your foot will learn. On the freeway use acc as much as you can for now. Hi regen actually feels more linear to me. Reduced seems to grab hard at the end.

I just never understood issues like this. The only thing I can think of is that you're overthinking it - there has been so much noise about how regen is so different and takes so much effort to get used to that I think it makes some people try to actively figure out what to do if they want to brake, and that makes it harder than it should be.

I was the same way; having read a lot of posts about how "different" regen braking was, I was worried about using it and whether I could learn how to do it, but it took me literally 5 minutes or less to get used to regenerative braking the first time I tried it on my Rivian test drive.

When my wife took her own test drive, I didn't want to try to have a long discussion about how regen braking worked and what to do / not to do. So what I told her was, if you want to slow down, ease up on the accelerator. If you think you need to brake, then brake! using the brake pedal. That's all it took - she also was able to get use to regen within 5 minutes without me telling her she was doing it wrong or anything like that.

If you think about driving as, you must be either on the accelerator or on the brake, then I think you will have a problem. But I am used to driving a manual, so I am used to engine braking when I take my foot off the accelerator, so I don't find regenerative braking to be a problem since it is very similar.
