Since I've started commuting to Gurgaon every day, I've noticed these things.
1. People would show a hand on a national highway and expect you to stop right away when you're driving at 50-60 kmph.
2. If you give an indicator for a left turn, there's always somebody who will overtake you from the left and go straight.
3. There's always one guy with a superbike with hazard lights on, doing stunts with a spider at his back. A chick basically.
4. Bigger cars are the most impatient.
For no God damn reasons, there are barricades with tents at the road, narrowing the road between Sultanpur and Arjangarh causing a 17 minutes jam. Maybe I am not aware of the reason yet.
And, the smog and dust situation is pretty horrible.
