The Marauders (Harry Potter):
James would be the one driving, half of his attention on the road, and the other half dedicated to composing (rather horrible-sounding) ballads to woo Lily.
Remus would be sitting in the back reading his book peacefully, a worn suitcase holding a heap of unread books he bought just for the occasion, on the seat next to him. Ignoring his friends with much success (he had a lot of practice).
Sirius would have been the first to call shotgun even though no one actually bothered to contest with him. He would be sticking his head out the window, whooping so loudly he disturbed several other people who drove past them. And he would glance at the side mirror every now and then to admire his reflection, and make sure his hair wasn’t getting too mussed up.
Peter would be encouraging James and giving him equally horrible suggestions to add to the nonsensical concoction of words he called a love song.
this was fun. if you liked it, and want me to do another fandom, just comment below!!!
