Guys..My wife's driver got Something like this few weeks back in a similar situation. But in his case, he just asked Wat d hell and the other guy (He was from the royal family) chased him & stopped his vehicle infront of him. After an apology he let him go not without a strict n strong warning.

In this case he happend to be more civilized so no man handling and abusive words

Moral of the story Dont mess with local guys eventhough they are at Fault
