Work has been eating my time for the last month, so I havn´t been here at all.
I´ve read through most comments on the subject now and I voted YES.

But only since I believe there are too many blurry and small/distant vehicles listed. The amount of background vehicles doesn´t really matter as long as the captures are good, in my opinion. Even if it´s a background vehicle and maybe just a part of it, the details shown might be of great interest for the enthusiast restoring a car like that. Just as an example.
So I belive they fill a purpose from the view of the auto historian. If you don´t want to see them, there´s always the possibility to make a sorting of the stars.

And it´s good to have the debate to try to find some consensus on what´s worth listing since it´s not always easy to draw the line.

There have been comments on cropping and such of the captures, I believe that as far as possible the capture should be left in full size. At least on the main picture.
But for identifying purposes a collage with parts from different angles like Ralph does, or these with contrasts, are very good. But I think they should be put in the comments.
