How does RelativeDistanceCondition calculate distances?

RelativeDistanceCondition checks how is given value compared to longitudinal, lateral or cartesian distance.

This value specified by the user can only be >= 0 which I guess enforces that calculation of distance is symmetric (absolute value). That would mean that on the Image 1 bellow we would get the same lateral distance d regardles of how we measure: A->B == B->A == B->A' == A'->B. Assumption is that A and A' are the same object just symetrically positioned around x axis of B by value d.

1. Is this correct assumption that lateral distance calculation is symmetric?

2. Is symetric when we are calculating longitudinal distance (Image 2)?

3. Which of the distances bellow is longitudinal distance (Image 3 and Image 4)?

Case on Image 3 bellow works even if entities are on different lanes on the same road.

4. Do we calculate longitudinal even if entities are on opposite road sides (Image 5)?

5. I assume routing is also taken into consideration (Image 6), but we have to be careful here because this is not compatible with point/question 4.
