There is a bias for overtaking on the left versus overtaking on the right. To disable this bias the following settings must be taken: - lcOvertakeRight=1 (or option --lanechange.overtake-right) - lcLookaheadLeft=1 - lcKeepRight=0 (not sure if this is relevant for you situation but it definitely introduces a bias in lane usage)
