Life (emergency) corridor

I have seen ambulances driving with their voice signals on many times, but many people did not want to create an emergency corridor. Cars did not give way, stood in the ambulance's path or changed their place at the last moment, only creating more confusion. I have even seen people honking at other cars that wanted to give way because it would slow the traffic down. Is it the „I do not give a s*it, it’s not me dying” attitude or just inability to drive properly?
