[My Cousin Vinny] Was Mona Lisa Vito’s testimony necessary?

Vinny is sitting in the courtroom right after the prosecution rests.  He’s looking at the picture of the tire marks and that’s when it clicks that he’s wrong and runs out to grab Mona Lisa.


He obviously knew all of the same information that ML knew, because he gives Sheriff Foley the make and model of car to research.  

Couldn’t Vinny have just recalled the Expert Witness from the FBI to start laying out the problems with his expert opinion?

1. He knew that Mona Lisa knew the car stuff way better than he did, and possibly more than the FBI's expert witness did.
2. This is his first criminal trial. Maybe later in his career he'll have the confidence to cross a witness like this.
3. His motivation is that he just loves to argue with this woman. It's like foreplay to them. We saw them drive off into the sunset _arguing_. Not kissing.
