Barter Grounds, still have features that hub does not, like disabled lockpick. Some new players wanting to buy a vehicle from other player need to trust another player (we all know that trusting strangers is mostly a bad idea) lot of caps and follow him to his tent or take a long trip to barter grounds to trade a vehicle like Verti or corvega. Same as some players are focused on barter and they could populate barter grounds if it would be more accessible. Last but not least Hub is a troll town. For me this suggestion is a big +1
