Riddle me this

You know those puzzles where you’re shown a picture and told there are a bunch of things wrong with it? Well, this is the screenwriting version of that puzzle, and you get to play detective!

In the following short scene, there are a number of problems I would flag if this were a proofreading assignment. Can you find them all?

INT/EXT. HIGHWAY - DAY (LATER)

Ashlie is gritting her teeth behind the
wheel as she eyes a sign; “Road Block Ahead”.

               ASHLEY
          (To himself)
     Your not gonna catch me pigs.

How many things did you find?

Please comment with your answer, below! I’ll be back tomorrow to update this post with my solution and explanation.
