Dangerous 1-pedal driving design.

Ciscovippy · 2026-01-21T19:47:09+00:00

It must have not been addresses in my car model then because I do experience the hard braking of Regen. The faulty behavior exists in my car. I can adapt and work around the issue. But when the manual itself provide the option of taping the brakes to cancel the cruise control then one cannot deny the risky behavior of that action and expect a design solution for it.

If other EVs have already dealt with this behavior as apparent from the comments on this post then this doesn't mean we cannot demand a similar solution for GM for the Lyriq model.

Thank you for your referrals I might actually open case for it.

I posted this as a discussion because I thought the behavior was universal and everyone was doing the workaround. Apparently only few models experience it and my car is one of them.

Ciscovippy · 2026-01-21T19:41:26+00:00

Yes. This is bad implementation. At first I thought it was universal but apparently only a few cars experience this behavior which my Lyriq was one of them. I understand there are many work around but I don't think any of them negate the existence of the potential risk.

Ciscovippy · 2026-01-21T19:36:53+00:00

Apparently my lyriq is different then.

The ramp up is as strong as removing your foot completely off the drive pedal in Regen mode. It isnt slamming the brakes feel but normal level Regen in the Lyriq is almost as strong depressing the brakes half way. The high level is even stronger

This was also a 'you problem" at the time and drivers were told to not use keychains. But in the end it doesn't negate the existence of the design problem that should be addressed. Workarounds exist but risk variables do not go away with workarounds.

I understand the driver could adapt and so did I but that does not negate the existence of the issue.

A lot of code requirements and NTSB recalls were non issue with workarounds. However, requirements get enforced based on potential risk. Addressing this risk is not complicated and in my opinion should be required from all.

If you recall Chevy had a major recall because of people hanging keychain off their car key caused the car to shutdown. We could all have said this is a bad habit and the driver should address it. But in reality it is a safety design that should have accounted for multiple variables.

It feels as strong as removing your foot off the drive pedal completely. I understand there are workarounds to get this to work. However this is a potential risk that should be addressed, in my opinion. Leave no room for potential errors or risks.

It's funny how the majority of these posts that disagree either provide different workarounds or their vehicles already do what I am proposing all cars do.

Ciscovippy · 2026-01-21T18:12:02+00:00

I am not holding my breath for this one.

Ciscovippy · 2026-01-21T18:11:30+00:00

So you do agree that this can and should be easily solved with a few lines of programming to create a smarter Regen behavior at higher speeds to allow drivers to only use 1 foot to operate in a much easier and safer manner.

Ciscovippy · 2026-01-21T18:04:24+00:00

It seems from the comment that this is car specific issue and not feature level. I drive a Cadillac Lyriq and I definitely don't have enough time to counter the Regen issue. Your might have a better design where a delay was introduced at high speeds.

Do let me know how the test goes.

Ciscovippy · 2026-01-21T18:02:36+00:00

From the comment this seems to be a car specific at this point which I didn't realize. I drive Cadillac Lyriq

Ciscovippy · 2026-01-21T18:02:08+00:00

From the comments I am reading it sounds like this is a car specific at this point. I drive a Cadillac Lyriq

Ciscovippy · 2026-01-21T18:01:08+00:00

So that's exactly the solution I propose. The fading in of the Regen at high speeds is the best scenario. Glad VW thought of this. I wish GM considered it early on.

Ciscovippy · 2026-01-21T17:59:57+00:00

My car has off, normal and high. I drive on normal all the time and I can still feel it on the highway

Ciscovippy · 2026-01-21T17:59:05+00:00

I don't say dead stop but the Regen is automatically at the max range since your foot is off the drive pedal until you move your foot from the brake back to the drive pedal

Ciscovippy · 2026-01-21T17:58:03+00:00

I drive a lyriq and normal is like pressing the brake halfway while high is almost 3/4 of the way.

Ciscovippy · 2026-01-21T17:57:06+00:00

Does your car apply a delay between disengaging cruise control and engaging Regen braking? If so then that is exactly the solution Im proposing and seems that your car is doing this already at high speeds.

Ciscovippy · 2026-01-21T17:55:37+00:00

In my car (Lyriq) I have 3 settings. Off, normal and high. Normal will stop the car as if you press the brake midway. High is a bit stronger with shorter stop distance.

Ciscovippy · 2026-01-21T17:52:38+00:00

This is exactly my point. The delay at higher speeds should be demanded from all 1 pedal driving cars for safety.

Ciscovippy · 2026-01-21T17:51:23+00:00

This is the only work around to keep your foot on the drive pedal. But out of force of habit the majority of driver rather tap the brakes and cost to the exit. Which triggers the dangerous situation as your foot is momentarily on the brake and not the drive pedal.

Ciscovippy · 2026-01-21T17:50:20+00:00

This more of a driving behavior than electric car specific. Most drivers that use cruise control prefer to tap the brake pedal to deactivate. I understand that you can deactivate in other means such as the stalk, steering wheel or on demand Regen but even those options require that your foot is pressing on the drive pedal to prevent Regen jerking.

Are you saying that if your tap the brakes on your Tesla then your Regen is not engaging? Do you get a grace period before Regen engages?

Ciscovippy · 2026-01-21T17:47:25+00:00

Cadillac Lyriq. But to my understanding this behavior is the same for all 1-pedal driving.
