FLS, that may be, my experience contradicts this. When I was on Verizon fiberoptic, I cannot recall a collision take place that I did not see or understand. So I think lag has something to do with it, unless you can offer a better explanation.
To illustrate. If I look three plane lengths behind where I think I am and a guy still lands hits on me, how is that different from flying through the space where he thinks I am and I actually am?
Gunnery is not calculated on the shootee's FE, it's calculated on the shooter's FE. What you see when other people are shooting is not exactly what they're seeing on their FE. What you see when someone shoots at you doesn't affect what's counted, because if the bullets hit on their FE, you take damage, regardless of what you see.
Collisions, however, are calculated on both peoples' FE. So if your plane is 3 plane lengths behind you on his FE, and he flies into that plane, he takes damage. From your FE, you will see him pass 3 plane lengths behind you and take damage, while you will not take damage, because he was 3 plane lengths back on your FE.
