to be more specific. Say I am on a long car ride and have no opportunities to stop for a rest room, would it be smarter to sip water during the car ride or something else?
((obviously the smart thing to do would be to not drink during the car ride thats just the best way I can explain my question))

Mildly, yes. Caffeine is known to have some mild diuretic effects (stimulates your need to pee) as long as you don’t have a [caffeine tolerance](https://pubmed.ncbi.nlm.nih.gov/19774754/).
So, anything that contains caffeine might make you need to use the restroom more frequently depending on how much caffeine was in the drink and how often you drink caffeine. Juices on the other hand appear to have basically no diuretic effect. Well, there are some really weird juices that *do* anecdotally have diuretic effects but they are weird things like parsley juice (and I’m guessing are talking about things like apple/orange/grape juice).
If anything, juice is likely to make you pee *less frequently* because they usually contain so much sugar that any water in the juice will be needed to process the sugar in your body since your body can only process simple carbs with water. (Which, by the way, is why you get so thirsty after pigging out at a Chinese buffet/on pasta/etc.)
EDIT: like someone else pointed out, you can definitely drink so much of anything though that your body can’t process it in time and just needs to get rid of it!
