Just wanted to chime in ... We're in the middle of a road trip from Dallas area through multiple spots in Colorado with our GGT. Has the option of taking our X (free supercharging and fsd were pulling me that way), but ultimately decided to take the lucid to have more flexibility on the range/stops. Super glad we did! Besides the range, with 3 kids and a dog, the room and comfort is just much better. The fit and finish also 1000x better than the X (had multiple service appointments to get rid of rattles, but they would inevitably return). Going on about 15k miles on the gravity now and is still as quiet as ever.
As far as the maps, I was one that was waiting on Android auto to be available and was hoping I could run both at the same time. Was disappointed when I couldn't and just ended up using the native maps more to take advantage of the 2 screens. Funny things happened, as I continued to use it, I kinda started liking it more than Google maps. 3.6 was also a game changer with the Google search integration. I do still double check to see if better options/routes available with Google maps, but have been more satisfied with Here recently. The one exception may be in city driving during peak time traffic, where Google just seems to have better traffic data.
Regarding fsd vs dream drive, it's not really a comparison. Dream drive reminds me auto pilot from 2019 or so. It's very helpful for highway driving and just good enough to be dangerous by making you think it's better than it is. Ultimately, it's great for long road trips with my hands on the wheel, but fsd is really unbeatable right now. Having said that, given how well lucid does everything else, I'm willing to wait on their self driving updates as I did with Tesla.
Overall, I'm very glad I brought the lucid on this trip instead of the Tesla. The headlights are amazing, especially with 3.6 and the range and flexibility it gives us with charging stops has been wonderful. I know with the model x I would have been stopping quite a bit more, especially with the wind/altitude (also cause I would have probably stuck to only Tesla chargers for the free charging

).
So while I understand the road trips are very different on the east coast, through Texas, New Mexico and Colorado, it has been fantastic!
