Basic questions about one pedal driving (Full regen?)

[B1050]

Can I assume that when "one pedal driving" the car will achieve maximum regen when you take your foot off the gas and you are decelerating? Can I also assume that pressing the brake pedal on occasion will be beneficial to keeping the calipers from seizing?

You are correct on both points, although I don't think you need to worry about seizing calipers. Your brake pads should easily last 80,000+ miles with regen braking. You will undoubtedly need to use your brakes in routine driving as regen will not always stop within your desired distance, or when needed for evasive maneuvers. Using your brakes will also remove light surface rust on your rotors which may develop during rainy conditions while you're parked. Hope this helps.

Yes correct.

Our brakes on our 2 EVs have been so far shown very little use for the most part.
One is at 75,000 miles and still have 50% pad life remaining while the other at 35,000 miles has over 80% remaining.

However 1PD IMO is something that should be an option for those that demand 2PD driving.

In my 2PD driving, I still get regen at all regen levels. Both EVs have mild regen allowing for coasting and no lurching in stop/go traffic.
I prefer not to have full harsh regen when lifting my foot off the pedal as I have to drive in congested traffic everywhere and other drivers cutting me off causing nausea / car sickness quickly.

If the Slate only has "Tesla" type harsh non adjustable regen, then I will have a problem with that.

Brakes actuate to hold the car one stopped, No worries about seizing.

Wondering if the Slate will offer the "auto brake hold" feature and if it's user selectable.

Bolt EVs have an excellent 1pd algorithm. Brake regen modulates so light lifting off the go pedal has less regen than foot all the way off. Smooth from coasting no regen to full regen. Enables brake light and holds at full stop. Some Other ev regens aren’t as nice.

As a matter of detail; most if not all EV’s that use regenerative braking also provide a mechanism to adjust the level of regeneration employed when you let of the ‘Go’ pedal.

My wife doesn’t like full 1PD regen in her Kia EV6. I on the other hand do and use it on Lightning. So I turn the Kia up to Max when I’m driving it.

My 2021 Mach E is still on original brake pads at 103K+ miles with plenty of life left in them.

1pd exclusively

Both of my EVs are on one-pedal, it's amazing and I literally hate driving gas cars now. However, on every trip that I drive I still make sure I use the brakes a few times to prevent seizing.

Love one pedal. Came down Fancy gap this morning. Gained 2% battery and never touched the brake pedal once.

Test drove a Honda Prologue for the wife and it had 1PD enabled which she said it made her sick with the traffic during the test drive.

We never drive with 1PD in our EVs, it's always 2PD.

When we returned to the dealer, salesperson showed us how to turn off the 1PD and go back to traditional 2PD.

Sort of spoiled the purchase experience and wife didn't want to complete the deal.

like many things you need to practice. You cant just lift of the gas, feather the gas and let the car slowly slow down. 1 pd driving can feel exactly like driving with 2 pedals.

Just like you dont slam on the brakes, you cant just suddenly lift off the gas pedal like you are used to doing.

Don't know where you drive, but in Los Angeles, we drive with the brake pedal covered all the time.

When I drove the Prologue in 1PD, it was impossible for the car to stop in time with all the traffic cutting in front of you.

If I relied on the throttle pedal, I'd rear end cars all day in LA traffic.

It's definitely about practice. Also, the regen in my Tesla isn't as sensitive OR as "hard" as it is in my Silverado EV (the Prologue has GM "bones", so regen/1PD is probably similar to my Silverado EV).

With over 30,000 miles of roadtripping in our Teslas though, you can definitely do it in heavy traffic. We've been to DC, Atlanta, Nashville, Chicago, Tampa, and so many other places and I exclusively use 1PD. Yeah, there's the occasional brake tap, but most of the time 1PD stops fully for me.

Yes, if you drive exclusively 1PD then it's a matter of practicing.

But I also drive white fleet vehicles (government exempt cars and trucks) and they are all 2PD.

So to prevent muscle memory issues at my old age, I'd rather not get into an accident with my 2PD and 3PD work vehicles as I would have to endure: blood drug draws, BAC test on site, driver's license & government insurance checks, lots of paperwork, and have highway patrol report on the spot even for a minor fender bender.
