What the hell is going on with the construction work in nagpur??

Recently in prajapati nagar , a big cement rock fell on a car (MG hector)! The whole windshield and roof was destroyed.. luckily no big injuries occured!! Bhai chal kya Raha hai yeh? Bridges ke beech m jagh hai toh bas cement laga diya , koi barabar kaam nhi horaha. The thing that's good is it was the car..if instead of car there were two wheelers , or other vehicles ..the person would've been straight up dead!!
