Orbital mechanics.
That’s why.
It isn’t heading our way at all.
Cometary debris streams follow defined paths.
That is how meteor showers are predicted and defined.
The debris streams tend to stay in predictable locations.
Right now we are entering two streams, quadrantids and geminids.

Well ISON is supposed to pass directly over the North Pole, 41 million miles straight up.

And the last pictures of it show a debris trail twice the width of the sun, so about 1.5 million miles.

But ISON still has 80 million miles to go to reach us, and the 1.5 million mile debris trail is expanding like a shotgun blast.

So the big question is, how wide will it spread?

Again, not wide enough to be a threat.
That v you are talking about is mostly volatiles.
A big yawn burger.
The dust likewise is a mostly yawnburger.
Look at the current November omega orionids.
They are a debris stream from a cometary source.
They are..a yawnburger.
Shows up real nice on radar.
But pathetic visually.
And that v ain’t aimed at us at all.
And won’t come anywhere near us.

You're one of the few who is getting the big picture.
