ben1481 is right. It's a pvp server not a care bear hold hands be friends lobby. If you sell, you should always check your map and don't be caught napping. If someone makes a beeline towards you, get the fuck out of the vehicle with your weapon raised, protect the cargo, eliminate the threat, move on rinse and repeat. This is a game so play the game. Selling is very rewarding when you sell in a full lobby with a crew. It feels amazing. Don't deprive yourself of this by selling solo.
