Ram Raiding is a useful way, used by Criminals, to get money by themselves or with friends! You can do this without being in a mission, and without being completely scared of Enforcers and other players.
The cars we talked about in the Vehicles section have a certain amount of slots for items dropped from storefronts and pedestrians. The Ceresco has 25 slots, for example. Here's a breakdown of the different items and their different points:
--Small: (Cell phones, jewelry, etc.) These items are on the player themselves and do not need to be loaded into a vehicle (as notated by a box with a number next to it in the top right part of the screen. The limit on how many small items that can be carried is 50, these items get the least amount of money from contacts.
--Medium: (Cameras, suitcases, etc.) These items cause the player to walk slightly slower while walking back to their vehicle, and must be loaded into the trunk. These items take 2-4 points from the max carrying capacity of the player's vehicle. These items get a moderate amount of money from contacts.
--Large: (Safes, TVs, etc.) These items cause the player to walk significantly slower and as such makes it easier for the player to be witnessed while carrying the item to/from their vehicle. These items take 5+ points from the max carrying capacity of the player's vehicle and must be loaded into the trunk.
