Dean was just getting the hang of coordinating his moves with the way the car shook with them, which moved them past the initial awkward phase and things were definitely starting to get good.
Tricia definitely didn't have a curfew, unlike many of the girls he'd occasionally tried to get to come with him to his motel room from school. Maybe because she was out of school already, even if not that much older than him.
But of course, when she did get lured by his kisses... dad was there, so the motel room was sort of kind of out of the question. But they were leaving the next day, probably, and he couldn't miss the opportunity, right? But dad being there meant that the car was there too, and, well. That was its own chance, right there, right? Even if he was a big boy and even the Impala's back seat wasn't infinite, she was dainty, and in the end it wasn't working that badly.
...now that he wasn't thrown out of balance, or rhythm, as it were, by the way the car shook. It was getting good, and her gasps and small moans were definitely telling him it wasn't just on his side of things. He swallowed some of them by kissing her sweet mouth again. This was better than kissing girls in school closet, to--
The door of the car opened, hard, and it took Dean about as much time to register who would do it like that as it took his father to grab him for the scruff of his neck and start pulling him out.
John wasn't happy with Dean for using the car so. John wasn't nice with Dean about it either, and he growled at Tricia too, to dress up and get the hell away from his son, while throwing Dean's jeans at him and then pushing him in the direction of their room rather roughly.
(But Sammy would probably see, if he woke up, that, despite the attempt to look contrite - and John's anger, Dean's eyes were still gleaming. It had been good, even if it got interrupted in the middle of things. And, well, leaving tomorrow would mean that the petite redhead wouldn't hold it against him?)

When it was Dean who noticed the car shaking, years later, he did nothing of the kind. Sam had somebody on top of him on the front seat (which must have been kind of even closer quarters, but whatever flew his boat...), he definitely didn't try to drag him out or, in any way, show him he was doing something wrong. (Hopefully. They'd already covered condoms.)
No, he just rapped on the passenger side window and gave him a thumbs up...
