Thanks to 'Pulverdings' for the tip.
"Pedestrians in vehicles appear further out from the player to allow for long range sniping" What exactly does this mean?
You would see empty cars driving when using the sniper rifle a few blocks down.
They random people driving cars probably used to disappear before the car did for LOD / performance reasons, or they just forgot to increase that when the increased the draw distance for other things.
The AI driver/passenger of a car has a longer clip distance before they disappear, so you can snipe them from a longer distance. I remember this annoying me on the 360.
