DreamDrive Megathread

I didn't notice that Lucid was selling a "hands-free" feature until I saw it on Gravity:

Something is cooking behind(4 lines), hope this gets before EOD.

I mean EOY but i am ok with EOD

Just did first trip with new 25gt.. and fist experience with real world dream drive pro.. and good golly is southbound 101 from SF to LA a workout of “stay in your lane”. At least 20times in large sweeping turns, the car would like to swerve into other lanes.. activating lane warning. Then my favorite at 75mph, when the fast lane would occasionally have an exit or merge on the left.. the car would jerk to go to that exit or merge before rapidly deciding to ‘stay on the highway’. Wife caught on quickly when she saw my deathgrip on the wheel whenever one of those situations would approach so we didn’t go sailing into oncoming highway lanes. I would have to be prepared for each oncoming one to either turn of highway assist or hold the wheel so tight that it would reject the initiative to want to change into another lane.

Strangest of all.. is on long sweeping bends on the highway, instead of the car maintains the smooth curve of the road, it makes multiple adjustments as if the curve is segmented/facetted..like not enough resolution of the spline that makes up the turn in the computers solve for how to move the wheel to make the turn. It’s so obvious. (My day job has me thinking this way constantly). You can see/feel it in the wheel. Wife would keep asking me if I was doing it! Never encountered this in the Merc EQS+ I had for a a week. This is what kept us feathering into other lanes on long sweeping turns.

Seems strange to not have your driving computer not understand the road when there’s a perfectly good (and smooth) map system on board to borrow high resolution data from so we’re not thrusted into an exit lane or going around a turn like your playing a 1970’s driving video game.

Other than that… best drive to LA ever. Period. Looking forward to drive home.. taking 5 north to maximize speed/time.

Interesting, I've done the reverse almost the entire way with HA enabled and didn't experience anything you are describing. I'd reach out and see if you need your system calibrated.

There is something wrong with your car. I have driven that exact route multiple times. There is *one* bug I ran into on I-5, but on the 101 it just… drives perfectly. I’ve done that road at least 3-4 times with HA on.

Call service; you need calibration or something. If you have timestamps, that’s even better.

Please heed @borski's advice. I had the same repeated 'white knuckle' experience back in the days before Lucid activated more (if not all) of the sensors that HA employs. I took the car in to service for recalibration, and the improvement was dramatic! Then, when a recent OTA update activated those additional sensors, there was an even more dramatic improvement. It's not perfect, so remember the rules, but I think you'll be very pleasantly surprised at the change!

Agree. Since day one it’s been like this. I remember turning HA on when first driving the car home from Millbrae. I occasionally see ‘sensor fails’ but then the alert goes away (or did I it!?). I have an appointment in a few weeks to address the sensor warnings. So it’ll all be connected, I’m positive. So happy to hear that dream drive is better than what I’m experiencing.. cause I’ve had several “I paid extra for this!?” thoughts on the long (but beautiful) drive yesterday. I’ll vid cap the effect on the way home. Good idea w the time stamp. I can pinpoint on a map precisely where it would happen!

 

[Joelaron]

precisely a few of the areas on SB-101 when the HA would jerk to the left exit and back:
(34.7105000, -120.1793167)
(34.7010323, -120.1674975)
And where it nearly put us in oncoming:
(34.6528228, -120.1827929)

I drove that stretch last Friday with HA activated and had no such problem. I would definitely ask your local service center to recalibrate your system.

Quick update for the drive back from Los Angeles. Same issues before driving back with the occasional swerving into other lanes but the alarming thing that happened was about the point that the rain started to get heavy on highway five and I went to go reactivate dream drive and all I heard was “boop” sound and it would not reengage the dream drive. Every time I tried, I would just get that sound. I was manually driving at that point for about 100 miles noticing that my side view mirror cameras were not present in the dash anymore. I also started to get sensor failures, and then the Lidar blocked warning. When I pulled into a charging station, none of the cameras were working. I did a soft reboot of the car, but that did not fix the problem. After getting back onto the highway is when the air conditioning system completely failed causing the windshield to fog up. The rest of the story can be read on the “app 2.0 update” thread. Lucid support walked me through a hard reboot and that allowed the cameras to come back online, but it’s also when my phone completely stopped connecting to the car with the app. They want me to bring the car in for service ASAP on Monday, so we’ll see what happens next!

Going south into SF…HA decided to nearly drive me into the median. Going in for service tomorrow, but woah. I do not move the wheel.. HA initiated the first hard rt, and the death gripped the wheel to take over. This shit is deadly. Look how far over the yellow HA had me! Clip here.

Again: something is wrong with your car. I would suggest not using HA until service checks it out.

Agree. Soon after that happened were several ‘radar’ and sensor failure alerts by the time I got to the GG bridge. Car goes to Millbrea when they open tomorrow. Been chatting w my service person from there the entire time. All day today, side view cameras non op, and all I see on left side of dash is a constant graphic of who has their seatbelt on. For sure, this feels like a ‘manufactured on a Friday afternoon’ feel. more update later after the car goes in. But.. holy crap did I have a great time abusing sprint mode for a bit today.

*side note update…. Dropped car of at Millbrae (love their staff! Travis = ). Drove a loaner fleet car (‘22 Dream) home.. VERY different experience with HA…. Wow. So much better. And can confirm to another thread topic.. lot more motor whine, but who cares cause it’s so amazing to drive.)
