Sigh. As someone who just made two different 27 hour drives across the country in the last 6 months, I can tell you this is completely fine. Driving on major US highways you will always be able to plan it out and find one. Plus, I took longer breaks of that size anyway because every 2-3 hours I needed to get out of the car and stretch. Having forced time to get out of the car for a longer trip would have been beneficial for me.
And what if I want to drive on roads that are not one of the handful of major highways?
And what if, unlike you, I can manage to sit down for more than 2-3 hours?
The mental gymnastics are so weird to read. It's like .. for a horrible analogy, you're trying to defend a power drill which no longer drills, by saying "well hey, it works just fine, as long as you want to use it as a hammer and not as a drill, and hey, having to rotate it manually to actually screw something in is actually a good thing because it's good exercise".
