This causes problems for behaving people though. a friend and I always drive together. sometimes one of us will have an intermediate stop that the other doesn't. In this case, I drop my trailer someplace out of the way, and go explore the town, working towards 100% explored. Many of the sites are narrow, and it's much easier without the trailer. What does lowering the distance to 100m gain people? Nothing. you can still block a driveway with a trailer, and move across the street, so your cab doesn't get hit.
So I see no gain from this, and plenty of loss.
