Why Didn’t Tori Just Walk To School?

The inciting incident of “Driving Tori Crazy” is that Tori and Trina have to take the long route to get to school because a movie is being shot on the route that they usually take.

While it is true that you cannot drive through a movie set, you can still walk through a movie set as long as it's not in front of the camera. So why didn’t Tori just walk that route to school? Considering that it supposedly takes only 5 minutes to drive that route to the school, walking it would’ve taken about 15-20 minutes. I’m sure that Tori would’ve rather done that instead of riding with Trina
