Adaptive Cruise - why does it require manual intervention from 0mph to resume driving in stop-and-go traffic

[LuvLucy]

Apologies is this had been covered (I could not find it in search).

Can anyone explain why when the vehicle comes to a full stop (0 MPH) with adaptive cruise control the user must manually intervene every time to resume forward motion? The car obviously knows traffic is resuming and pulling away and it even displays a message saying "Traffic Cleared - To resume, togged Set switch up or press accelerator".

What would be the logic behind this (I fail to think of any) - why would the car not simply resume when that message is displayed? I find it rather annoying to constantly be hitting thee accelerator or fiddling with the set switch in traffic.

I Luv Lucy…

Fortunately, they have recently improved this and if you are facing forward with your eyes open there is no need to toggle the switch. It automatically resumes, no problem.

Since you don’t have the DDP I can see why you’d be confused tho.

It doesn't. The most recent software OTA made improvements in this area. From the owners' manual:

Isn’t this a DDP specific feature? I thought that was the case in the past. Anything below DDP was manual resume I thought.

Hmmm. Perhaps, from the screenshot it looks like it should just be DD, and DDP… not sure.

I do not see this behavior on the latest software - 2.6.16 with dram drive premium. Still have to manually resume ever time in my car - it never automatically resumes.

 

[HC_79]

It's a DD Pro Feature only so if you only have DD Premium its not available

Thanks @HC_79 I think you solved @LuvLucy ‘s question.

Lame cash grab from Lucid, this functionality should be available to DD prem.

I disagree, the price on DDP has come down considerably and the development costs are astronomical and ongoing.

When I bought the car it was a 10k upgrade, and the differences that sold me needed to justify the price. Here I think those differences are well worth $2,500.

Not sure I agree. My recollection is that originally there was no DD Premium. One either got DD or DD Pro. Many complained that DD didn't have 360 cameras (primarily) and Lucid responded with Premium that provided that feature. So Premium is essentially regular DD with the camera package.

So long as Lucid itemized what is in which package, I don't think it is a cash grab as such.

Seems lame to me - clearly the car with DD premium knows in software when it should resume - it displays a message telling you such. Does not seem to need any hardware.

Also IIRC DreamDrive Pro was $9K when I boight my AT a few months ago and it was unobtanium on inventory cars - most none of them had it (probably because nobody wanted it at $9k). If I wanted DD pro at the time I had to custom order and wait an indeterminate time.

Sometimes, software costs money. And using it as an incentive for people to upgrade to DD Pro is reasonable, imho. It’s not a “killer feature,” but a convenience feature.

Agreed, I might be a happier man if I didn’t have the convenience of reading these threads while Drive Assist happily drives in the background…

It’s a nice feature, but with how great this car drives it’s not a need. $2,500 is a small price to pay for the software and hardware upgrade.

Re @LuvLucy you can still design and get a custom Air ordered via Lucid, so if you didn’t see any stock ones to your liking it’s an option for other people to go that route.

Also, writing this post while being driven feels a bit like Cigars at the Ritz… (inspired by the Queen song)

I paid $169,000, almost 4 years ago, for a premium car with a lot of advertised high tech features that I still don’t have. It's time for Lucid to deliver the level of software that other manufactures have. The fact that the Gravity might have better software really doesn't help me.

I actually feel like Lucid has delivered on the vast majority of what was promised.

The drivetrain, range, performance, interior quality, and even things like DreamDrive and the core UI have all matured significantly. It’s easy to forget just how much was packed into this car from day one. OTA updates have filled in a lot over time and while some of the more advanced autonomy features took longer than expected, the car today is far more complete than it was at launch.

Gravity might be the next chapter, but I think (know) a lot of its software tech will trickle down to Air. Lucid hasn’t abandoned early adopters they’re just building iteratively, and I’ve seen real progress. I get that not everyone feels the same, but from where I sit, they’ve come through on most of the big promises.

Sure, “more polished” is an argument and a feeling people have. But the car was what it was when you bought it. If it had stayed the same it would have still “worked” at least to the level you test drove it.

It’s a lot of money, and I believe lucid has continued to deliver for those original early adopters. I know they have for me.

What? We were talking about resuming from a stop in ACC or HA, which works fine and doesn’t require manual input with DD Pro. I know this because your DE (and mine) came with DD Pro, which has this feature.

Yes, there are plenty of other software features that aren’t there yet, though only a couple that were promised. Those weren’t the topic of discussion (there are plenty of other threads for that), so let’s stay on topic.

So if I understand it correctly, the behavior I’m describing is the “Extended Stop and Go” feature only available in the “Drive Assist” functionality of Dream Drive Pro and has been defeatured in DreamDrive Premium?

Lucid does a really poor job of explaining what DDPro does. I had no idea how to read “Extended Stop and Go” at all when I was purchasing.

Also still kind of lame that they take it out of DDPremium IMHO clearly it can do it they just left it off. Rather annoying and pointless IMO. But then again I don’t know why a HUD is neeeded for ambient lighting

build your own car then you can make all the engineering and design choices yourself and have it all make sense

No. It was never “defeatured” in DreamDrive Premium. It never existed for anything but DreamDrive Pro, so it isn’t as if they had it and removed it.

Lucid does a really poor job of explaining what DDPro does. I had no idea how to read “Extended Stop and Go” at all when I was purchasing.

Came out in an OTA in the fall of last year (September ‘24 for US, November ‘24 for Canada), and was described as such:

Extended Stop and Go
On vehicles equipped with DreamDrive Pro, the auto-resume functionality for drive assist has been enhanced. In heavy stop-and-go driving, your vehicle will now resume traveling after stopping in traffic as long as the driver monitoring system detects the driver is looking ahead.

This was one of those OTAs that was a major update, but happened to arrive just a few months before you got the car. Feel free to read more at https://www.lucidupdates.com/ota-updates.html

Okay.

But then again I don’t know why a HUD is neeeded for ambient lighting

“…Dynamic Ambient Lighting is tied to the HUD wiring, so for now, we can’t offer that feature without the HUD. The good news is that this is just a temporary supply issue.”
