Curious why some do not use 1 pedal driving.

[MaintGrl]

I tried the 1 pedal mode when I was experimenting with what my new truck could do. I drove for a day or so in 1 pedal, and really missed the coasting effect that 2 pedal provides. I just haven't had the patience to go back & try it again. And . . my other vehicle . .a 96 Ford Ranger XLT is 3 pedal, too

A friendly rebuttal:

If you feather the accelerator pedal (don't lift your foot completely off) you can modulate the amount of braking applied by the 1pd. You can still "coast" in 1pd by finding the sweet spot in the accelerator. Sounds difficult but it became second nature within about the first 5 minutes of driving my old MME with 1pd, and now on my Lightning. The "physics" of driving are still the same. If anything, it's more similar to engine braking with a stick shift or old style automatic transmissions that stayed "connected" when letting your foot off of the gas vs the newer automatic transmissions that feel like they completely disconnect and allow coasting to try and eek out extra gas mileage.

And I appreciate that immensely, and respectfully! You do you. My point is that 1 pedal driving requires behavior modification and learning a new way to solving old problems. Which is a characteristic of early adopter consumers like you and I. There is however a finite number of those willing to do this.

Even in your new scenario, driving in the snow, in reverse, and parking in a parallel spot with 1pd introduces new risks that the overwhelming majority of people are unwilling to undertake, so we need to be clear and understanding of that reality. As opposed to being dismissive and saying "well, this is how I work around it" which is the route taken by most owners on many of the hurdles facing this truck from range, to limited charging options/speeds, to unlocking the most efficient driving style. It's just not for everyone yet.

Thanks for the reply and perspective and have a great day!

One pedal for "hand to hand" driving because it improves reaction time (for me anyway) and two pedal for long highway drives when I like coasting

Keeping in mind that I do not have a Lightning yet, so have never had the opportunity to drive a vehicle with 1 pedal mode. However once I do, I will drive multiple vehicles that are all 2 pedal vehicles. In an emergency I don't want to have to think which vehicle I'm in and how to panic stop.

The brake pedal still works in 1PD.
I don't think an actual panic stop feels or executes any differently between 1PD and 2PD.

I am a 2PD driver for all the reasons others have mentioned but mostly because I am old and my mind is half gone already. I drive my wife's ICE almost as often as I drive my own. I don't want to mess with my habits and reflex if there are no perceived benefits. Also my foot gets to move more using two pedals (a positive in my book).

To give you some idea about my first point. Once I took my wife's car to the shop because the windshield wiper pump was not squirting water. He called me back and said they can't duplicate the problem. When I went to pick it up, he showed me that it works. That is when I realized I was trying to use the controls in my other car (flashing high beams expecting the water to come out). I kept quiet about this embarrassing event for over a decade but I am too old to care now. I am all about streamlining the routines now. Maybe I can delay the inevitable move to the nuthouse.

I see many references to not needing brake jobs when you use OPD. There is actually NO DIFFERENCE between OPD and 2PD with respect to the use of regenerative braking vs physical braking.

OPD vs 2PD is a personal choice and only shifts how the pedals work. Energy efficiency is the same and the use of physical brakes is the same for the same driving style.

• OPD - Regenerative braking on when you ease up on the accelerator pedal and begin to decelerate and on full when you remove your foot from the accelerator. Pressing the brake pedal engages the physical brakes.
• 2PD - Regenerative braking on the first part of the brake pedal, pressing harder engages the physical brakes. You can see this happening on the clam shell guage when it turns green initially. If you pay close attention, you can feel when the physical brakes engage as you push harder on the pedal.

In both cases, regenerative braking is used first and physical brakes are only used when braking more aggressively than regenerative braking does. This means your brakes will last the same in either case and is much more dependent on how hard you decelerate.

OPD will not crash your truck in slippery weather however you do need to learn where the point between power and regenerative braking on the accelerator pedal in OPD. If you hit ice, removing your foot completely from the accelerator will apply regenerative braking and potentially cause grief if that wasn't your intent. Practice a bit and you find the exact spot for zero power. It shows you on the clam shell gauge. Practice this on good roads because when you hit ice, you don't want to be watching the gauge. If you drive OPD for any period of time, you will naturally learn this spot and it becomes muscle memory. If you are new to OPD, make a note to learn this. Staying with 2PD is perfectly fine if OPD isn't for you.

We have this Lightning and an i4 as well as a couple of gassers. One of those is a hybrid and the other we don't drive much. So a week ago I was driving the hybrid and stopped to fill it up. I spent multiple attempts and 5 or so minutes trying to get the pump to work out of the WRONG HOSE! Finally broke down and went into the store for help.

So, after 50+ years of driving and < two of those EV I have already forgotten how to pump gas. That seems like some rapid unlearning.

My driving is almost exclusively not-heavily trafficked highways or rural roads. I can absolutely see the utility of 1pd in heavy traffic and could possibly see myself using it more if it wasn't for how cruise and 1pd drive interact, at least in how I use the car (and I use cruise a LOT).

Mostly I find myself using cruise but frequently using the buttons to disable it and "coast down" due to something way ahead. But ultimately there is quite often I don't have my feet on the pedals but also want to slow slightly.

I quite prefer the setup in our i4 which allows you to switch modes by move the shift lever (conveniently filling my right hand at rest) either left or right. I just wish it would default to 1PD rather than 2PD or at least let me program which is the default.

I have seen in some threads that some don't use the 1 pedal driving and I wonder why. I took a 60 mile drive yesterday and only had to use my breaks twice. At the rate I will likely never have to do a brake job. Plus a little energy recovered.

I drive on Sport Mode. It enhances the regen braking so it's a happy medium.

What’s wrong with how 1pd interacts with cruise? I’ve got Blue Cruise and have only driven in 1PD and haven’t noticed any issues. It’s actually smoother than my model 3 with FS D was.

My issue is the transition off of cruise, specifically that if I am disabling cruise I am doing so to slow down, but likely not as much as 1pd drive does. In that case I don't want to put my foot on the gas pedal to find the right "spot" between acceleration and deceleration that I am seeking, but if I disable cruise to slightly slow then suddenly I get the aggressive deceleration of 1pd drive.

I'm not saying it is a truck problem, the system work fine, it just doesn't mix with my driving style or location. That is another part of it, with where I am not speeding up or slowing down frequently, and I have lots of time to plan ahead. In that case 1pd drive doesn't offer me any benefits to make it worth adapting my driving style. Now if I lived in the city with more heavy traffic, or traffic lights, then I could see changing how I drive an using 1pd drive more.

Regen rate on 1 pedal is too high for my liking so to coast I’d have to keep my foot on the pedal. That doesn’t really solve a problem in my mind. If other like it, more power to them

This is definitely a bit of a learning curve but I can say it is simple muscle memory now. 2.5 years with our MME and 2 years with the Lightning and my foot automatically goes to the right place on the pedal when I want to kick off the cruise. It definitely took a couple of months to build the muscle memory.

I liked that feature immediately!
