[sumo-user] Leader bug in junctions in SUMO 1.6.0 (and 1.8.0)

[Daniel Urieli <daniel.urieli@xxxxxx>]

Hi,

I believe there is a bug in leader detection in lane-merge junctions.

In the attached image, we see an ego-vehicle in the middle of a lane-merge junction, whose previous leader suddenly stopped being its leader after this previous leader exited this junction. Instead, the ego-vehicle's current leader is a vehicle that has just entered the junction in a neighboring lane, *behind* the ego-vehicle (in fact, behind a few vehicles that are behind the ego-vehicle). 

Is there a fix/workaround to this issue?

Thanks,

Daniel
