Sounds more like either an actual compliance or preventative CYA compliance thing if you ask me.
If they think they need to show you this (for whatever reason, their legal department said so), then it has nothing to do with bad UX design but really, being in between a rock and a hard place. If my legal team made me do this, I'd also show it every single time, because you have zero guarantee that the person driving the car this time is the same person that saw and accepted the dialog the last time. Even if you think about "driver profiles", that totally goes out the window in a rental car scenario for sure and even in a non-rental one, not everyone that has a car that has "driver profiles" will make use of the feature.
So as a dev I would show this for whatever period of time legal required me to show it, to CYA for the above cases and then I'd just close it because I don't want to annoy people so much as to actually require an actual "click" on the accept button.
