How did you do that?
If you go into the editor and load the map (needs to be done for both freeplay and dfreeplay maps for those with EM4 Deluxe)
look at the virtual objects, find the following objects;
policestation_turnto
policestation_park01
policestation_park02
policestation_park03
policestation_turnto needs to be moved further up to the edge of policestation allowing room for you to make three extra objects the same as policestation_park01,02,03 but name the new ones policestation_park04,05,06 (I changed the numbers so that they were all in order from 1 - 6).
You then need to edit the LAToPoliceStation script to include park04, park05 and park06. Also edit LACallPatrolCar script to include same and the jobs done. This will allow you to park up to 6 vehicles out the front of the Police Station and will allow patrol car back up to respond from these parking spaces when requested.
I am happy to provide the edited map and files if anyone would like them, but would only do so with Hoppahs permission.
Hope this helps
take care
