This sequence is equal parts Terminator 2 and The Matrix. That's really all you need to know. Watch it long enough and you'll see the protagonists drive through a double decker bus like it's no big deal.
Singham's a cop, and he's kind of a badass.
There's just so much going on here. At one point, the hero's being dragged by horses, so he does the splits, directly into a light post, knocking the horses' riders to the ground, before continuing on. Balls. Of. Steel.
In the world in which Khiladi takes place, physics have been turned on their head. Cars explode towards the direction from where they were shot, and random vehicles fall from the sky already on fire. Cars that weren't even in the scene before making their downward appearance. Outstanding.
