Not possible to turn off 1 pedal driving?

[macb00kemdanno]

My R1T was the first EV I've owned, and also the first daily-driver I've owned that *wasn't* a manual transmission. So 45+ years of driving a manual -> one-pedal driving.

For me, it was a trivial transition. As in, I had one-pedal driving figured out within 1/4 mile of driving on my first test drive (Nov 2021).

I had totally over-thought this. But it doesn't require any intellectual effort at all - you just get in and drive, and pay attention to the feedback between what you are doing and how the car is responding, just like any other tool you might pick up for the first time.

Pretty much this. I’ve driven manuals, automatics, CVTs, dual-clutch transmissions, EVs, hybrids, diesels… you name it. I adapted to the driving requirements of each and went about my day.

I adapt to the car instead of expecting it to adapt to me.

As for which results in better range - coasting or regen braking - on the highway speeds without lots of stops and gos, coasting increases EV range more than regenerative braking because energy conversion is never 100% efficient. Coasting allows the vehicle to use its kinetic energy directly to keep going.

Why is it so hard to convince people that simple laws of physics still exist? I have been in many arguments that turn into vicious personal attacks trying to explain that using the kinetic energy to end naturally is always going to get you further than capturing the energy as regen and reusing that energy. People honestly believe that you capture more energy in regen than you lose in distance. If that were true, then you could build a perpetual car that captures regen and keeps going.

The problem probably lies in the very vague word "coasting" and how people perceive that context. And also, most people have no understanding of how EV motors and their controllers work.

Coasting an ICE car with a manual transmission would mean putting it in neutral or holding the clutch, right? Most cars with an auto trans or DCT will effective do that for you. Modern autos do coast, with little friction. But I'm not aware of any EV that does actually fully decouple the motors from the tires with a physical disconnect. Our quad Rivians can disconnect the rear, not the front.

At that point, you cannot coast in the sense of simply freewheeling without energy going into the motors. You can "coast" by holding the accelerator, either physically, or with software automation, to give you the same illusion. If you think that doing this in software, such as what the Bolt does, is actually somehow conserving energy, then you are one of the people who doesn't understand physics.

I absolutely cannot stand 1 pedal driving.
Why oh why would they not make this an option you can disable on the R2?

Two things to note:
1) this is not a Nissan; have you test-driven any other vehicles and confirmed it's jut not your cup of tea?

2) the way to get to less of a feeling of one-pedal driving is by lowering the intensity of regenerative braking in a Rivian.


At the end of the day, completely free-wheeling in an EV does reduce the range, and the vendors will probably cater to the market the same way as manual-shift transmissions are a niche offering.

My Polestar lets me coast. My EX90 lets me coast. Taycan and Macan EV let you coast and only regen when the brake pedal is pressed.

Cars that don't offer this seem to simply not want to do the hard part of blending braking with regen, or lack the additional hardware to do that properly. I get that it's a hard problem to solve, but it is a cost-saving feature. When asked as to why they don't support it, they point to efficiency when in reality, that isn't the case.

I've compared OPD to coasting, and in reality, the range difference was not noticeable because generally when using OPD, I find that I keep pressing on the accelerator and find the "coasting" speed where the car is not moving the motors or regenerating.

I am passing on the R2 because I find one-pedal driving uncomfortable. I have tried it over and over in the EVs we own, and it is just not comfortable to traditional 2-pedal driving.

THIS! I had a deer jump out in front of me. With regen in the R1T, it was breaking way sooner. And I missed hitting it by inches. I am pretty sure that if I did not have regen on high or an ICE vehicle, I would have hit that deer.

I'm teaching my teen to drive with the Rivian. I will agree with this sentiment. His current training is "If I panic let got of everything, the truck will stop".....while not permanent, and arguably a bad habit to start with, it's an easy thing to teach, and an easy thing to learn.

*sarcasm*
Yeah, I had to stop buying stick shift cars because whenever I would let go of the accelerator pedal, it would slow down rapidly in 1st, 2nd or 3rd gear and that is just unacceptable. I expect it to coast. Until manufacturers make a stick shift that costs even when in gear, I'm not buying another one

*sarcasm*
I only love cars that brake hard as soon as I release the accelerator even though there is a second pedal that does this anyway.

IMO it's safer (and every driver training authority and vehicle manual you check will agree), especially in less than ideal driving conditions. I just set my regen to "low" when i want more of that "coasting" experience, but it's one less thing to go wrong if the vehicle decelerates, rather than keeps coasting like automatics do, let alone vs. my guilty pleasure of putting it into neutral on a manual car.

I don’t get people’s aversion to 1 pedal driving, once people get the hang of proper modulation of the foot instead of on and off it is so much better. Even the ability to modulate speeds on a twisty road is better.

Pretty sure anyone with stick shift experience will adjust quickly but anyone should be able to adjust and master it in a few days. 1 pedal driving is one of my favorite things in my R1S, wish my older Tesla Model S could do it.

If OPD makes you feel that way, great.

I can appreciate and acknowledge that different people can prefer different styles and modes of driving and that there isn’t “on true way” that everyone must model.

There is a lot of misinformation being dropped in this thread and dismisses 2-pedal driving as less efficient, worse, and insults being thrown as if every EV must be this way and can’t be like ICE cars as if that’s an insult.

My Ioniq 5 gives you ALL the options.
Level 0- no regen (coasting)
Level 1- low regen
Level 2- medium regen
Level 3- high regen
i-Pedel- One Pedal Driving
Auto- modulates regen based on distance to objects in front of the vehicle

Using the brake pedal blends regen with physical brakes depending on the force applied.

I‘ve ordered an R2 and I’ll probably use it like I use my Ioniq 5 and have the car make most of the decisions. HDA2–>Universal Hands Free

Don’t like regen, don’t buy an EV. At least adjust the regen setting and learn to modulate your right foot. Not hard.

Rivian is not a legacy auto maker trying to convince their current customers to go from a gas powered vehicle to an EV. They don’t need to make a vehicle that makes you feel like you’re still driving a gas powered vehicle. They engineered vehicles that are most efficient at what they do.

If you don’t like one pedal driving, don’t buy one. It’s that simple.

We’ve had our R1 since 2022 and it was our first EV. First time we drove it was at the factory in Illinois for delivery and then we had to drive it back to DC. We figured it out pretty fast. The software has improved the driving experience greatly since then.

I‘ll tell you what I don’t like, driving a Jeep 4xe that has one pedal until it hits 5mph and then completely lets off the brakes and just keeps rolling.

 

[electruck]

omg is anyone besides me getting super excited for the R3 already so that we can start this same pointless debate all over again with the 3rd gen of Rivian newbs?? I simply can't wait!
