Indeed, but I guess people are saying that it seems even worse since the driver was in the middle of helping someone.No, perhaps I didn't make myself clear. I'm well aware of the distinction. What I mean is all emergency vehicles at all times should be considered "on call". As in ready to attend an emergency.
i.e nobody should ever impede the movement of an emergency vehicle whether it's in a depot, on the street, attending a call or filling up with petrol.
