Nope.

This is true for everywhere I have lived in North America. Outside of NYC it isn't so much people not caring, as people not realizing that the siren is mostly to tell you to clear the way. A lot of people just take it to mean "stop where you are", when the actual intention is "move out of the way, then stop". I travel along a route near a hospital frequently, and it is incredibly common for people to be stopped in front of an ambulance, blocking the path, while the ambulance blasts their horn trying to get them to move out of the way.
