Part of the problem is for VFR drivers they have so much fancy stuff in their machines that not only does their flight pass by without hardly looking out the window they are heads down which actually puts them in a higher risk bracket for mid air collisions!
I recall the early days when GPS driven FMS's where being used for primary Nav flying across the ditch I watched an ANZ B767 opposite direction which looked like we where going to split each other down the middle!
