Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

For my partner, it's 100% the disconnect between the (lack of) sound the car makes and the degree of acceleration. They would feel like my driving was jerkier and less smooth, unless I put on the fake engine noise. They also felt like the car was fine when they were driving.
I could be a shitty driver I guess, but I've got the accelerometer data to show that I drive less aggressively than they do.
TLDR: People aren't very good and using regenerative braking in a smooth manner.
Definitely had an Uber driver in LA .ame me sick. Dude had a puke bag ready...( I used the door method and didn't mess the car...) ...I mean he could have just drive nicely
Yeah, I got an EV ride on Lyft in Seattle once, wasn't very long. But once I got to my destination I hurled. I drive an EV, to me, part of the "fun" is making the smoothest stops and starts possible. The Lyft driver was the opposite. The regen felt like it was on max, and he would go full pedal to the metal to no pedal at all.
People have been driving like this way before EVs... people just are shit at driving. Had a coworker long ago that I rode with one time, and he did this shit on the fucking highway. Speed up like 15 mph over the speed limit then brake hard to get his speed back down. Then on the roads, every stop or go was foot to the floor or brake, didn't matter. Dude just was shit at driving, and most people are shit at driving.
Before I knew about one pedal driving I thought Tesla drivers drove with one foot on the brake and one on the throttle because their brake lights would shine constantly
Humans have adapted to associate sound with movement in vehicles, experts explain. Because electric vehicles don't have the auditory cues and vibrations from the engine that we're used to, which indicate when the car is accelerating, this could trigger motion sickness, Di Giulio says.
Another reason is regenerative braking, the process whereby when drivers release the accelerator, the motor starts acting as a generator. This creates resistance that slows the car down and also produces electricity that can be stored in the battery. The accelerator needs to be released gently, or it can lead to harsh deceleration.
"It forces the person to perhaps feel like they're rocking back and forth for that brief moment when the speed of the car suddenly changes," says Hac.
This is something Carolyn Le, 24, from California, has noticed. She gets "horrendous" motion sickness when her friend drives her in his electric vehicle in busy cities, she says. The regenerative braking means it "constantly feels like the car is stopping all the time".

"It's actually horrendous," says Carolyn Le, who blames regenerative braking for her motion sickness
Electric vehicles can also accelerate and decelerate much more quickly than conventional combustion cars, which Di Giulio says can cause motion sickness.
Most drivers mash pedals and are either accelerating or braking.
Big Oil propaganda.
My EV has two drive gears, one that engages regenerative braking when releasing the accelerator (B) and the other that coasts, decelerating more slowly when you release the accelerator (D). The B gear feels like when in an ICE you release the accelerator in a low gear and use the resistance of the engine for deceleration. Releasing the accelerator in the D gear feels more like being in a high gear in an ICE where the car coasts a lot more.
If drivers are finding that regenerative braking causes motion sickness then the driver is not selecting the gears correctly (there are literally only two forward gears in my car, it's not hard). Or perhaps their car doesn't let them choose. I haven't driven any other EVs so I don't know how common that is.
You would get the same effect from a driver of an ICE vehicle if they drove everywhere in second gear.
Incidentally, driving everywhere in the B gear seems to be a common mistake (at least for my car model, when I first looked up the difference between the gears) because inexperienced EV drivers think that they only get regenerative braking in the B gear. That's not the case though. In the D gear you also get regenerative braking, you're just applying less braking intertia so you slow down less quickly, but you still recover the same amount of energy into the battery over a longer period of time. When actually pressing the brake pedal you also get regenerative braking, unless you brake hard and the brake pads need to engage to respond quickly. I tend to drive in D and only switch to B if I'm entering a lower speed limit area and need to slow down more quickly to match that speed.
It's not propaganda. It's a real problem with how some EVs are configured to aggressively apply regenerative braking even in the absence of driver input on the pedals.
I've been ranting at anyone who will listen that I hate "one pedal driving." It fundamentally breaks a long-standing driver control paradigm, that the throttle pedal accelerates the vehicle forward and that the brake pedal accelerates the vehicle backward (yeah yeah, we call it decelerate but still, it's acceleration). Pressing neither of those pedals makes the vehicle coast where any forward/backwards acceleration comes from air resistance, gravity on an incline, and rolling resistance of the vehicle itself.
One pedal driving tries to return the car to some kind of pre-Newtonian understanding of physics, where an object in motion still wants to stop.
And some drivers let off the throttle too abruptly, making for a terrible riding experience for the passengers when simply lifting the foot off the pedal makes for abrupt braking, with too high a jerk (rate of change of acceleration, or third derivative of position with respect to time). That's what makes people uncomfortable, especially passengers who can't mentally prepare themselves for changes in the driver's inputs.
I've driven and ridden in plenty of Teslas, and sometimes in the last 10 years they've defaulted to more aggressive one-pedal driving settings. When I test drove Polestars and Rivians, I couldn't tell if the sales offices configured one pedal driving or if that's the manufacturer's preferred default. Kias and Hyundais default to a lighter setting but it's still not the same as the typical ICE vehicle.
And frustratingly, Kias and Hyundais appear not to allow for regenerative braking on the brake pedal only. If you opt for smooth coasting, it doesn't regenerate even when you're using the brake pedal. It's a flawed UI/UX design.
This is a real problem, and EV manufacturers need to fix it. Give me normal cars that drive like normal and happen to have an EV drivetrain.
People often dont get that these gears/driving modes are only different mappings of the drivers inputs. At no time the car uses the friction brakes when it could also use regen braking.
Passengers? Or Big Oil execs? Who’s feeling sick?
Because I pay zero dollars for gas and I feel awesome.
This sounds like the “one pedal driving” feature. Which you can turn off. It’s not on by default (at least for the EV model I drive)— EVs can coast just like combustion cars.
The acceleration is fun when you first get one but it burns through your tyres. Most of the time I'm on my adaptive cruise control on any appreciably long journeys.
Adaptive cruise is my second most hated feature in my car. Instead of holding my preset speed and throwing itself into a corner, it backs off to old lady speeds at the slightest curve, making it effectively useless as a cruise control, and meaning that I can maintain a better speed with my foot.
Number one most hated is definitely the "lane keep assist" that tries to force me into the oncoming lane on those same corners unless I fight against the steering wheel.
I like it. When traffic stops, adaptive cruise control also stops so you don't hit the car in front of you. And when traffic starts again, the car starts again.
Not using cruise control is always better for gas mileage, but adaptive cruise control lets you rest your legs in traffic.
I've never had it slow down when the road curved, only when a car is ahead of me.
Dr Irene Di Giulio, senior lecturer in anatomy and biomechanics at King's College London whose research includes motion sickness, says research so far suggests some people experience more severe motion sickness in electric vehicles than in non-electric vehicles.
It's something Dr Nicholas Hac, a neurologist at Northwestern Medicine in Chicago who specialises in dizziness and vertigo, has also heard from some of his patients. "They just notice that they're much more likely or prone to be motion sick" in electric vehicles, he says.
"I've heard about it many, many, many times," he adds, saying about two patients a month specifically reference feeling motion sick in electric vehicles.

Lola Baird noticed that she felt sick in electric vehicle taxis as well as her boyfriend's car. "I started to put two and two together," she says
The accelerator is like a joystick from the old gaming days for flying games. I am learning how to use it properly :)
Duh...it's the same reason why people got sick in 1970s Detroit land yachts, heavy vehicles and weak suspension damping.
