@namdre commented:

in 5e54eb6 (aka r22871) reverting 5fe8c2a (aka r22870). It introducef thread-deadlocks. Also, despite locking myPartialVehicles, there was still potential inconsistency when calling MSVehicle::getBackPositionOnLane when the vehicle position is updated but myFurtherLanes have not been recomputed.
