I drive fire appliances, (apparatus) in central london, and have done for a number of years, i mainly drive ladders, and it can take us 10-20 minutes to get to an incident a mile form the station or our location at the time of the call, central london is notoriously ridiculously congested, and is in the top five off the most congested cities in the world, along with Paris, some south american cities, and ofcourse NYC, i have found that lights and sirens do have an effect, and people do try to give way or move over, but in cities like NYC, London and simmilar, the fact is there is just nowhere for anyone to go,, even if they had all the will in the world to let you through. I had a day shift last week, we had 6 calls in the morning, before the (!!)appliance broke, and we managed to get to just 2 of them, the rest we couldnt make enough progress.
I often just sit in traffic with the lights on for 5 minutes, no sirens,with people driving up onto curbs and beeping each other, in an effort to make space, but to be honest, if there is no space for anyone to move to, then there is nowhere for them, or us to go.
I think that is the case in NYC, yes you get people who just dont give a ratz cock that your an emergency vehicle, but the majority of the time, its just a case that there is nowhere to go, and with the additional problem of the police prosecuting drivers for crossing the white line at red traffic lights to let fire engines and ambulances through over here in London doesnt help.
I think its just the number of people on the roads thats the problem, more than the attitude of the majority of people on the road.
Lights and sirens do make a difference.
