You can also just stop at gas stations, refill, take a pee, and swap drivers.
But feel free to drive ‘Biden-style’ if it suits you! (-:
Here is the story of a girl on a mission with no plans to stop and be identified by gas station cameras:

Exactly; there’s nothing heroically difficult about driving 1000 miles. I used to drive from Tucson to Portland regularly. The first leg was 1000 miles or so, with two stops for gas, coffee, and to take a leak. That 1000 miles took about 17 hours, at which point I’d pull into a side road somewhere in the Modoc National Forest, sleep for a few hours, and finish the trip in the morning. Probably could have made it straight through, but I never did.
Coming back, I’d stop for a nap two or three times.
