I'm the opposite - the scarcity of infected people encounters is nicer and brings more tension for me than should they meet one every other scene. It doesn't seem illogical given the fact they're doing everything they can to avoid them and are in remote areas. Even in the mall episode where there's only one encounter, imo there was tension throughout the episode and it was properly built up.The lack of encounters with infected people has been a let down. The stress and tension from that element is really missed.
