I was driving home earlier on road through a town with a three lane road either side. On the opposite side of the road to me I saw an ambulance with blues and wailer approaching the junction I'd just been through from a side turning - so the lights for it were red. All three lanes had at least two vehicles waiting at the red light and the ambulance opted for the outer lane which had a Merc behind a Transit waiting at the line. As the ambulance approached the Merc, it was clear the Merc was willing to move but the Transit remained stationary until the light changed to amber and then set off to move out the way (nothing coming out the turning in front of them which I'd used nor were there any pedestrians I could see (there are almost never any there anyway). It could be the Transit did not spot the ambulance behind but with blues and wailer at night this seems unlikely. I tend to move out the way if I can although I am conscious you could breach a traffic light camera albeit that's never happened. My instinct is someone could be dying so it seems selfish not to but I can well imagine there are those who don't care and wait. Just made me wonder what people do in those situations.
