Are people in Bengaluru so insensitive to Ambulance Siren?

Today, near the Marathalli outer ring road signal, I felt really bad to see an Ambulance stuck in traffic. All drivers around the ambulance were looking at the vehicle that was emitting emergency siren. None of them tried to move away to give way to this Ambulance. The traffic signal is just 50 meters away and there were few policemen at the signal. None of these policemen made attempts to clear the traffic to get the Ambulance moving.

Even after the green signal, and the traffic started moving, several vehicles tried to move ahead of the Ambulance from the sides.

Did we loose the concept of 'emergency'? Why can't we understand that we should stop on a side and give way to emergency vehicles?
