Imagine: Bucky dating you Sam's now ex girlfriend.
You had been seeing Bucky for about two weeks now but there was a problem, you'd met Bucky while you were dating Sam. Sam was annoyed that you left him for the super soldier and still hadn't gotten over it. You talked to Steve about it and decided that the whole of his team (Cap's side in Civil War) should go for a day out. Bucky, Steve and Sam were in one car with you, Nat (I know she was originally on Tony's side but I love her) and Wanda in the second car and Clint with Scott in the final car.
Sam got into the car moving his seat very far back.
"Can you move your seat up?"
"No."
Let's just say Steve had to listen to them whining like children until you got to the beach.
