Regen braking non adjustable ? Deal breaker for me.

[metroshot]

Yeah, that is sloppy slop. It looks like jerky motion can be an issue, if the driver hasn't learned to keep their foot on the accelerator, and lift gently to slow gently. Taking your foot off means you want to stop relatively quickly.

Correct, it's a matter of lifting your foot slowly off the accelerator.

Some 1PD is harsh and abrupt (ie new Tesla w/ updated software = nausea).

Other 1PD is gradual and adjustable regen which makes it pleasant (ie Honda Clarity which has regen paddles on the steering wheel to control amount of regen).

And then there are others who have driven over 40 years using 2PD and 3PD which makes muscle memory difficult to adapt to 1PD.

I prefer 2PD as a personal preference choice in my BEV and to avoid any muscle memory confusion/issue while I drive work government ICE vehicles.

Last thing I want is to get involved in a car accident and explain to the state police plus have to deal with mandatory blood draw for drugs/alcohol.

I'm still perplexed.

I scooped this up with my AI Slop Ladle:

Driver Preference and Control
Comfort and Control

• 1PD: Some drivers find it more enjoyable and easier to use, especially in stop-and-go traffic. It can lead to smoother driving experiences.
• 2PD: Offers more control for those who prefer to manage braking manually, especially in complex driving situations like steep hills.

Situational Use

• 1PD is often preferred in urban settings or when driving downhill, while 2PD may be favored in rural or highway driving where more control is desired.

Conclusion

Both driving modes have their advantages. The choice between 1PD and 2PD often comes down to personal preference and specific driving conditions.

While AI can say 1PD is enjoyable for some drivers, I don't like it.

If 1PD were adjustable and the harshness can be reduced driving in urban bumper to bumper drives, I'd be all for it.

Unfortunately everything is going towards harsh regen and lurching behavior with EVs in heavy traffic - especially noticeable in the new years Tesla models w/ updated software.

If I lived in suburban or rural part of the US, 1PD would be fine as I don't have drivers jumping in front of me, cutting me off and having to jump on the friction brakes which causes the lurch and nausea.

My plane has friction brakes activated by both feet above the rudders and it does not have 1PD....

I wish my 2022 Model 3 would work this way. Even if I lift off the accelerator quickly, regenerative braking takes a few seconds to ramp up to full.

No jerky surging here. But that's just me.

Yeah, that was referring to the more aggressive regen on vehicles like the Teslas mentioned. In those cases the 1 pedal is basically a speed control, where what would be coasting on an ICE vehicle requires the pedal to be depressed to a certain point, zero depression of the pedal is to stop or nearly that, full depression is max speed, any speed you want in between is a % depressed in between those.

What did you ask the AI to get this? What question is it answering?

It looks like "is 1PD or 2PD better?" and it answered "depends".

Tab is gone now, but my query was something like "What's the difference between 1PD and 2PD in an electric vehicle?"

It was a long answer. What I posted was just the tail end of it.

 

[AZFox]

Best I can tell there's a lot of variation in how 1PD is implemented.

I hope Slate's implementation is driver-friendly for the type of driving the Slate is designed for.

Here's an article I found when searching for information about 1PD:

What Is One-Pedal Driving? Why It Might Be the Most Fragmented EV Feature Yet
It can boost range and help save your brakes, but it’s also a feature with wildly different approaches depending on the automaker and customer preferences.

What's so good about having an adjustable Regen Braking? I want it to stop when I let off so I don't wear out brakes.

Adjustable regen braking allows for much less brake use - way less than I expected.

My PHEV after 90,000 miles still has the original OEM brakes at 65% - driven with adjustable regen paddles on the steering wheel in 2PD.

My BEV after 45,000 miles still has 80% brakes left - driven in 2PD (engaged regen mode).

Teslas have a very harsh 1PD mode that can't be adjusted so I am hoping Slate will take this cue and allow for drivers to choose their regen depending on where one lives.

I wouldn’t want to pay extra for this feature. Otherwise I’m all in.

I'm in agreement. Surely to goodness the regen would be dialed in to a reasonable (not jerking stop) level. I love 1PD and it takes a short time to get used to it by my experience.

If you just lift off the throttle and let the vehicle come to a stop, it'll do so like you were hitting the brakes. When you stop, the front suspension unloads and you rock back in your seat. Just like with using the brakes, if you want it to be smoother when you come to a stop, just don't use full lift.

This can seem counterintuitive at first to "hit the gas" when continuing to slow to a stop, but all of my family members have picked it up in a drive or two, despite everyone thinking it is very strange at first.

I've noticed with Rivian if you lift off abruptly, it does not immediately go full regen. It ramps up quickly. This helps keep things smooth at the expense of having to possibly use the friction brakes more often. But it has such strong regen that I still rarely use them.

Have you driven a '24 or '25 Tesla ?

They have harsh lurching if you pull your foot off.

In Los Angeles, we drive with our brakes covered at all times.
Idiot jerks who love to cut you off are the norm.

 

[beatle]

Yes, a Model S and a Cybertruck. They're about the same, more responsive than Rivian. They're fine. They are better than the earlier S/X that didn't have blended braking, so in shoulder seasons and winter, you might have little to no regen depending on how warm the battery was. There are small indicators of this on the screen, but they still make for unpredictable driving.

I am not sure why you continue to mention Los Angeles like nobody else has any aggressive driving. This is not the Olympics of traffic suffering.

Simple, you don't "pull your foot off" abruptly, unless you intend to stomp the brake, which is of course going to be jerky anyway. Almost taking your foot off, letting the pedal up to like 5-10% and you will slow without the jerk.
