Do you give way when you hear/see an ambulance coming?

I do. It's quite obvious that almost all cars would stop or give way for the ambulance because everybody knows it's an emergency. This morning I saw a different situation, a car was about to park when an ambulance was fast approaching. It's so sad that this car didn't give way. It had his car park before the ambulance can pass by, and not only that, this car was so slow that the ambulance has to wait. After the incident, the driver of the ambulance came off the van and went closer to the car's driver. We don't have to hear what he said, it was obvious on the ambulance's driver's face how disappointed he was. It's a sad thing that some people don't care enough for others. They don't realize that a little care would be more than enough to even save a life.
