Well, perhaps in the fanfic, Harry is driving a Muggle car for some reason, maybe he's on a mission in the Muggle world. A Death Eater, who has learned to use some strange Muggle - magic hybrid spell, targets the car. The car goes out of control and crashes. Harry survives but now has to figure out how the Death Eater managed such a spell and stop them from using it again on other unsuspecting wizards in the Muggle world.
One possible plot could be that Harry is on his way to Hogwarts in a magical car (like the Weasley's flying car). Suddenly, they encounter a powerful dark magic spell that causes the car to malfunction and crash. Harry then has to use his magic skills to save himself and his friends while also dealing with the threat that caused the accident in the first place.
In this 'Harry Potter car accident fanfic', it could start with Harry and Hermione going to visit Hagrid in his hut. They decide to take a magical car that has been enchanted to travel on land and water.

The car crashes into the riverbank. Harry and Hermione then have to deal with the angry house - elves while also trying to fix the car to get back to the castle.

Well, perhaps the car accident in the fanfic is caused by some mystery element. Like someone was trying to stop Amy Fleming from reaching a certain place related to a horse - related mystery.

In a fanfic, a Harry Potter potion accident could lead to all sorts of strange consequences. For example, the character might end up with unexpected magical abilities or physical transformations.

One possibility is that a potions accident could cause a time - related mishap. Maybe the potion was supposed to be a simple Sleeping Draught but due to the accident, it creates a time - loop.

Perhaps in the fanfiction, Harry is under the influence of a dark spell that causes him to hallucinate a car accident. This trauma could be so severe that he starts self - medicating with a dangerous magical substance, becoming addicted. Or maybe he's on a mission in the Muggle world, gets into a car accident, and while in the hospital, he's given some strong painkillers that he then becomes addicted to. But it's important to note that this is all very much against the normal Harry Potter narrative and more of a creative and often disturbing exploration.
The fanfic could center around Harry's life outside of the main events of the books. For example, it could explore his summer holidays in more detail. He could be spending time in the Muggle world and using his magic in creative ways to solve normal, everyday problems.
