Must be a Honda disguised as a Mustang as it was able to crash but not hit any pedestrians. 

It is possible that this car is not a Mustang at all. Notice that there are no pedestrians anywhere near the point of impact.

Good. Seriously fuck this guy and everybody like him. They actually slow traffic down because everybody needs to brake to let them in.

This is how a pit stop works.

That was all Perez, he started to move to the edge then started to drift back. After he got passed by Ricciardo, he should have just yielded his position to Vettel and Massa and stayed out of the way with his compromised car.
