I don't get it

What don't you get about it? Activate VATS and you'll see a glowing trail leading to your closest objective.

I did I do not see the glowing trail I have the ps4 I pressed l1 to activate vats but it just went into targeting mode

Wait a moment !!!

Are you sure you have the VANS perk ??? -> http://imgur.com/bd7Xiv2

Secondly, just press L1 (for a second) on your PS4 joystick, and you will see something like this: http://imgur.com/BADMIgJ%C2%A0

I pressed l1 and nothing

You have to have your weapon ready and an enemy in sight...then you activate it, pick a body part, hit the attack button as many times is called for then hit the action button to start unloading.

You also didn't answer the question about actually having the perk


VATS =/= VANS

I have vans I noticed a glowing line when I go into vats but than it disappears

I assumed it was a typo ha

Is mthe VANS really worth the point? Seems pretty pointless to me considering you can place markers on the map and follow the compass.

From what I understand the marker only shows in vats meaning that depending on what your focused on you can't see fully the green line or rather bread crumbs so yeah it's pretty pointless

If you hold down the V.A.T.S key (Q), you can enter V.A.T.S mode without enemies in sight. Useful for V.A.N.S.
