The other thing, if you are ever in a vehicle without a siren and with a light on, and even with a siren, is to just see how motorists actually react to it. Again, I'll invite anyone who sees an ambulance, a fire engine, or a police vehicle approaching an intersection to just see how the public behave. Actually, if you have an inexperienced, ill-trained driver behind the wheel of the vehicle with a siren, as you will know, it could actually create more danger—create more of a peril situation if you don't actually approach it properly. Just imagine the scene where you are sitting on the motorway, as described by Mr Brown, and all of a sudden you've got this orange light flashing behind you. I suggest that any driver who is in that situation, trying to get to the sort of situations he described, is not going to get very far just with a little amber light going on. No, what they will do is they will put their hazard lights on, as I have seen many a dog control officer do, racing off to a scene. They'll probably be tooting their horn, and they may even be—going back to my little situation down on Lambton Quay—having some sort of PA system emitting all sorts of noises trying to attract attention.
