They'll update so if you are playing solo online without being in a party, they'll put you in a game with people in your geographic area so you'll have less issues peer to peer.
However people do like to play with their friends on the other side of the globe or country so the yellow bars will have some prevalence in games where you are going to be in a party of a squad.
To tell you the honest truth tho I think it would be wise for future games with a good MP mode (good in regards to variety of modes, weapons, and maps not connectivity) to do dedicated servers. And as added incentive to make money offer a service of dedicated servers for games with top notch servers. People don't have to pay but than again Caveat Emptor if you don't wanna fork over money for better quality monthly (if you don't know latin it means Let the Buyer Beware)
