Emergency Vehicle/Red Light Question

[fazersharp]

I have done and would still do in both car and on bike using cautiously and safely.  any camera's would pick up the emergency vehicle crossing as well so I'd have my reason to appeal any fine

I think that the cameras take two pictures 1/2 second apart and the second picture will show that you were moving so by the time the blues get to your position you have had your picture and the bill is already in the post.
I would move over the line every time so long as there was no camera.
I always thought that traffic lights had a sensor on them that sees the blues and changes the light to green - or is that an urban myth.

The issue with going over the line is that when there is a que of traffic there is enough room to pull over but they cant because of the gap infront is not big enough so the one at the frount needs to move up a bit and over the line to give everyone else room to move over.
