Good point! I forgot that one. The lane changing for speed gain works by collection "motivation" over some time and then triggering a maneuver if the motivation exceeds a threshold. By default, the threshold for overtaking on the right is twice as large as for the left. With lcSpeedGainRight you can change this factor. With a value of 0.5 the situation is reversed. > On a side note, some of these parameters have a range that extends to infinity. For example, To set lcSublane to infinity, do you just write lcSublane="infinity"? No. You may write things like 1e100 though which gets you pretty close to infinity (-: Am Di., 10.
