Family is on a highway, daughter flirts with a guy. End up at same rest stop eating. He ends up taking her.?

Its a whole family. They are traveling across the highway on vacation maybe? she flirts with him in the car, walks in on him in the mens room at the food place. Its not the movie where the biker takes her and then the dad hunts them down. I dont think anyways. its something like it though 80s maybe?
