Like everyone said, why bother with non stop. You still need to take a bio break and stretch your leg.
In 2014, I was able to make the trip with two stops, one at Harris Ranch and one at Tejon Ranch. Tesla had spaced the chargers about 1/3 and 2/3 along that route, making it impossible to charge at one and have enough range for the rest of the trip. However, stopping to eat at Harris Ranch, leaving when I finished eating, and charging while taking a rest stop at Tejon Ranch meant getting the message "you have enough range to continue your trip" before my wife got back from the restroom. But it meant arriving with a relatively low state of charge, meaning needing a full charge if I wanted to make the return trip as fast.
With my wife's Model 3, stopping at Kettleman City meant getting the "you have enough range..." message by the time I was handed a menu in a restaurant. The trip itself wasn't any faster because it took as long to eat and use the restroom, but I arrived with more range.
I planned to take that trip in the Lucid but ending up doing it in the Model 3 because my daughter's car got totaled so I drove down there to give her the Model 3. Had I taken the Lucid, I would have been interested in whether I could have done it nonstop, but not because I would have done it nonstop. I still need to eat, and eating after the trip does not change the total driving plus eating time. It's an illusion if you think it's quicker, unless the goal of the trip is to have a meal at a specific place at the end of the trip. But if the Lucid can do it nonstop, it would mean being able to eat anywhere I want whether it's near a charging station or not. I'd still stop for a rest stop, and the advantage there is that I'm less picky about what restroom I use than I am about where I eat, so finding one where I can make a 15 minute stop should be fine. But if I have to use a restroom where there's no charging, a broken charger, a long wait, etc. I'd still like to know whether or not I could make it.
Ideally, I'd like to be able to make the trip without needing a charge, go to a hotel with L2 charging, and not have to worry about charging on the road at all, but charge if it's convenient. That would give me the most flexibility. And I'd prefer to spend a bit more time taking 101 than 5, since the latter is a more boring drive. But 101 has surprisingly few good choices for charging, while It's pretty good for finding Tesla Superchargers.
I think that it's great advice to tell people to stop no matter what. I've made that trip nonstop before when I was younger, arrived tired and with a headache, and still ended up spending enough time in a restaurant when I got there that by the time I finished eating it was just as late as it would have been had I stopped for a meal on the way. But I'd also like to focus on the initial question and know about real life experiences on a single charge, not exceeding the speed limit by more than 5 mph. I have a GT with 19 inch wheels.
