As Violet is driving to her big show at the end of the movie, she drives about 50-100 feet past the tolls and then turns around rather violently.
She then starts heading back towards the tolls for a VERY LONG period of time. Enough time.... for her to have gone crashing through the tolls and back to Jersey. The three members of the cast in the car had an entire conversation in the time she had been driving towards the tolls, and then she still had enough time and enough room to whip the car around AGAIN and head back towards New York.
