I should add that moonsense715, Apocalypse Rising Co-Producer, has vastly improved on bot AI and introduced them into APB for use during low player count games. The idea was to allow lone players to join up and experience a "populated" server while they hang out, and as human players join in they substitute in for the bots until the playercount gets high enough.
TSR 2 will be getting this feature as well, so players can enjoy some light action before the players start piling into the server.
