What do you do?

My friend Sugandhi Gadhadhar writes:

"1. The driver in an Innova that had "Police" marked on it was honking away. He argued that he *had* to do that, because he was on his way to duty, and others had to make way for him. And we were on our way to what, a party, at 8:30 am ?
2. We ask the car behind him to block the way, so that he doesn’t turn right from the leftmost lane that he was on. The driver in this 2nd car says, ‘I’m going right, why should I go left’ ?
3. Lump on forehead for obvious reasons."

What does one do when a police vehicle wants to break traffic rules?
