Ok, maybe an ePedal and a discrete brake pedal for those times when you just gotta stop?
It looks like exactly that in the image above. The ePedal has a separate switch to enable that functionality, but the traditional brake pedal is always on the left.

Just reading the comments, you can tell who has and who hasn't driven an EV. Almost every EV has the ability to drive single pedal. In the Volt, you put it the gear selector on 'L' and it doesn't actually change anything with gears, but it maximizes regenerative breaking so that when you let off of the accelerator pedal it begins to aggressively recapture that energy and slow the vehicle. On the Bolt it's nearly the same but even more aggressive. Teslas, Leafs, and just about every EV is the same. You realize that you don't actually need to use the brake pedal much.

Had Musk come up with the one-pedal concept, there would be people here wetting themselves in anticipation of such a great breakthrough. But, since it’s Nissan, well... Hate to break it to you but the Leaf has two pedals. The brake is still there

Don’t worry, braking is simple. All you do is lift up a little door next to the volume knob on the sound system, where there’s a keypad. You enter your 8-character password, using the letters on the number keypad as necessary, and signifying the “shift” functionality using the # key before entering the appropriate number/letter.
Then enter “0” to brake, “00” to stop braking, “4” to accelerate, and “1” to coast.
Passwords need to be changed every 11 days for security purposes, cannot contain more than two characters from the last three passwords, and must contain at least one capital letter and no words that could be considered crude or offensive. Any Nissan dealer will be happy to reset the password for you during working hours if you have three forms of federal identification.

That makes more sense. There'd be almost no acclimation period. One might have to practice to keep from inadvertently slowing more than that like but panic stops would still be second nature.
With the way the eBrake was 'highlighted' I thought it was the only pedal.

I would be one, but I am familiar with regenerative braking. I just never thought it applied a significant (aggressive) braking force. I equated it with older ICE cars that didn't have the idle set to 1100rpm or whatever. You back off the gas and you could feel it slow, but never at a rate I'd consider as touching a brake pedal.
I really would like a Volt. I see them all the time and mainly on the freeways. I always wonder how far they're going and the state of charge. They're never in the 'slow' lane and they're moving smartly.

They were probably talking about the leaf.
They didn't remove the brake pedal, it's just a driving mode in a lot of EVs (the Volt and Bolt both do it too) it's mostly for stop and go, heavy traffic as a way to efficiently regen power instead of using the mechanical brakes.
This. It's called regenerative braking.

Regen in our Volt is pretty aggressive. It takes some practice or your passengers will complain. But then many people mash the Go pedal hard every time the light turns green and then do the same with the Stop pedal as they approach a red light at the very next corner.
My brother-in-law does not rest his right heel on the floor when he drives so the vehicle is always and abruptly changing speeds every time he hits a bump or twitches or whatever which, after awhile, makes me car sick. It has the same effect on my sister so she always drives when they go somewhere together.
You adjust with practice. In five years all new cars will have batteries and regen. Sell your oil stocks now.

This^. No gears, one speed, the L is just for more aggressive regen. It is where both drivers in our family always put the shift lever. And I always use Sport mode for quicker accelerator tip-in. On the wide open interstate I may use D just so any foot movement on the accelerator pedal isn't very perceptible to my passengers.

Most new cars have auto-emergency stop. I would think that would be default as well!

Ah... So the brake pedal becomes the "Holy schmoley there is a problem" pedal. Yeah.. me no likey. I believe the Prius does it better... the brake pedal is for regenerative braking until you push a lot harder, then the actual brakes turn on. I would expect a lot of Leafs with the e-pedal will 'just not stop and crashed !', and they will stop having that feature. People need to be trained instinctively to use the right control. Adding complexity guarantees failure.
Sheesh... Stupid lack of human factors engineering.
Agreed. May the deity-of-your-choice forgive me for quoting my Ultra-Luddite Dad* on this: That sounds like the sort of thing that would be great as long as it works and works right, but a real pain in the butt when it stops working.
For me, the big question is "When do the brake lights come on?". Do they only light up if the "Holey Schmoley" pedal is pressed? In an ideal world drivers would follow at a safe distance and pay enough attention to the car in front of them to notice if it is slowing down even if that car's brake lights never light up, but unfortunately the world we live in is far from perfect and I can foresee a lot of Leafs (Leaves?) getting rear-ended by semi-attentive drivers because they slowed down with nary a flash of brake light.
*Seriously, he's trapped in 1959. He firmly believes to this day that "You shouldn't buy a car with automatic transmission, power steering, or power brakes, and especially not power windows or power door locks because they haven't worked all the bugs out of those systems yet and they quit working all the time". Probably true to an extent in 1959, no longer true by about 1969, and definitely not the case by 1979.
