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.
