I had to read through the rest of the thread but this post absolutely did not get enough credit.
1. Clearly busted out the ruler to make sure the lines were tidy.
2. Multiple colours to direct the reader's eye to the important parts.
3. Masterful use of labels so even the savages or 'Dopes' amongst us could still understand. Is there a median? Where is the median? Oh, there it is, thanks Sliver!
4. Arrows. Arrows are so underutilized today, but he uses them very effectively to indicate direction and to add clarity to the labels. Fabulous.
5. He even adds the dip#### ####wad, who leaves excessive space betwixt himself and the car in front of them. An ode to a CP classic GG!
6. Finally, the sheer effort. This was not jotted off when he was outside for a fake smoke break. This took time. This took thought. This took Sliver.
Bravo.
And I left the diagram in the original size as an homage. You don't minimize an artiste.
