Continuity mistake: As the popular kids are speeding past the school security guard, notice the last car a black pick up truck. There are six kids in the back of the truck. In the very next shot you can see there are only two kids in the back. Although one of the kids was crouched in front of the kids that were standing up and might have been obscured from view, the other three were sitting in plain view and have disappeared. (00:08:55)
Revealing mistake: Just before the security guard smashes his car into the oncoming car, you can see he has been replaced by an stunt dummy. (00:09:25)
Continuity mistake: When Matt, his friends and Danielle arrive at the party, Danielle is wearing a top where her cleavage is visible. When they enter the house, Danielle is wearing a different top where you can't see her cleavage.
Visible crew/equipment: When Kelly bursts into the classroom and pulls the main character out of the chair there is a shot of them from behind as they leave. There you can see the battery pack on the back of the main characters pants. (00:59:00)
Answer: While it doesn't have anything to do with the overall plot, the crash shows just how much Matthew is afraid to do the wrong thing and perhaps how he overthinks things. As we know all he would be doing is missing a bit of school by getting in his car and driving from the school. The fact that Matthew is able to imagine an horrific crash of a security guard because of just skipping school shows how worried he is about doing the wrong thing.
