I'm late to the party here, but I have a '25 Rivian R1S Trimax. In conserve, I can hit 400 miles of range at 75 or less, which is plenty for my bladder. The adaptive headlights, the hands-free ADAS system, and now with Google Maps nav make the Rivian an excellent choice for road tripping. As far as charging speed goes, it is slower than the Lucid but in my experience you are fueled up in 30 min per stop which is about perfect for using the restroom and stretching your legs. With the long range you're driving 3-4 hours before stopping, so it's not a big deal to charge a little longer IMO.
The Rivian is positioned higher, so its driving dynamics aren't as good on curvy roads as those of the Gravity, but its off-road capability makes up for that if you utilize it. The Ascend interior, found on the Tri and new Quad, is on par with Lucid's. I'd say the Gravity gains a point for real leather availability, but the Rivian gains one for overall design. The software on the Rivian works pretty well and the platform is more established, but Rivian's aren't without initial build quality issues. For example, mine needed servicing because someone from the factory didn't seat a connector for my rear defroster. It was an easy fix but I had to take it to a service center. Other than that it's been great.
The only other vehicle on the market in consideration for me would be the Gravity. The Cadillac escalade is too big, the vistiq doesn't have a frunk which is a huge miss. Tesla is a non starter for me as their "premium" ev's have a considerable down market feel relative to the Rivian or the Lucid. I will look at the Gravity again in a couple years, when hopefully there will be good availability of the platform.
