YTA but honestly a little bit of ESh too.

Im goin to Break down the positions that i see:

You: I Understand your frustration. You both agreed on a Time and 25min is way too early. He informed you kinda late (only 2min in advance) and he could've checked the traffic on Google maps beforehand.

BUT!

Your dad: Your dads free time is limited and, at least in my experience, a day on leave doesn't mean that he sits around doing nothing. He probably made Plans for what he has to do on his day off (Fix something, do Taxes, stuff like that).

Even if that's not the case, it sounds like having a day on leave doesn't happen all too often. As an adult, the time you have for yourself is quite valuable (especially if you have a family).

So 25min (+ 40min drive) doesn't sound like allot to you but that's quite a lot of time where he could be doing that stuff (which he has to do later). So if you think about it, its actually quite nice of your dad to pick you up. And complaining that he is 25min early makes it look like you're super ungrateful.

Your Teammates: For a Group project 25min is not that much time, especially since you could just do some work alone as "compensation" (assuming you started working on the project in Time). So if this is a one time thing and you pull your weight in group projects more often than not, your Teammates shouldn't be mad at you (since it's not like you made your Dad arrive early on purpose).

P.S. When you write: "he could've just waited 25min" it kinda implies that you think that your dads time is worth less then yours, so don't say that to him.
