If i test it on an altis life mission and we are 2 friends on the server 1 in each side of the map
then use a vehicle spawn point to get out 1 - 3 vehicles and move them around a bit and i then go back to my friend their just all inside eachother until i damage one or he gets into one
same happens when there is 40 players on so image that cluster**** xD
happens all across the map but there they just fly in mid air or stand somewhere their not.
