A summary was first published to congress, but I can't find any online reference to it:

Conflict of Interest Notice

Wikipedia's Law of Unintended Consequences
If you write in Wikipedia about yourself, your group, your company, or your pet idea, once the article is created, you have no right to control its content, and no right to delete it outside our normal channels. Content is not deleted just because somebody doesn't like it. Any editor may add material to or remove material from the article within the terms of our content policies. If there is anything publicly available on a topic that you would not want included in an article, it will probably find its way there eventually. More than one user has created an article only to find himself presented in a poor light long-term by other editors. If you engage in an edit war in an attempt to obtain a version of your liking you may have your editing access removed, perhaps permanently.

In addition, if your article is found not to be worthy of inclusion in the first place, it will be deleted, as per our deletion policies. Therefore, don't create promotional or other articles lightly, especially on subjects you care about.

If you have a close connection to some of the people, places or things you have written about in the article Solomon curve, you may have a conflict of interest. In keeping with Wikipedia's neutral point of view policy, edits where there is a conflict of interest, or where such a conflict might reasonably be inferred from the tone of the edit and the proximity of the editor to the subject, are strongly discouraged. If you have a conflict of interest, you should avoid or exercise great caution when:

editing or creating articles related to you, your organization, or its competitors, as well as projects and products they are involved with;
participating in deletion discussions about articles related to your organization or its competitors;
linking to the Wikipedia article or website of your organization in other articles (see Wikipedia:Spam); and,
avoid breaching relevant policies and guidelines, especially those pertaining to neutral point of view, verifiability of information, and autobiographies.

Question

What was the source of speed data? It all sounds fishy. Oh, yes, today's car may record speed in their computers, but it definitely was not the case in '64. Witnesses? Something scribbled by a road cop to fill the box? Or did he only consider the cases involving a thorough investigation of the crash, with expert opinions etc.? The article needs to elaborate more on the data and its limitations.

I recall the only serious accident that I was involved in (as a driver). I was speeding (just like the whole "pack" did) 90 in a 60 kmh zone, in heavy rain. Saw the stop light just a bit too late - the wheels locked in the very end of the braking, when the speed was (my guesstimate) below 30. Evading collision, I skidded left, hitting a high curb at around 20, and came to rest hitting a concrete column at around 10. None of these numbers appear in police records: there were no radars or witnesses on site, and no need for further investigation (no one was hurt but the car which rear-ended me one minute later was practically totalled). How would this case appear in Solomon's stats?

Hi East of Borschov. Let me do some research and see if I can answer your question in the article (or, rather, you can once I find an appropriate source). It may be that there is nothing published on this, in which case I'll ask Mr. Solomon and get back to you, although we might not be able to update the article with that information. It might take me a while, so be patient.Ludasaphire (talk) 11:28, 6 August 2010 (UTC)[reply]

Another question

What does "mean operating speed" mean (in Solomon's theory) when different lanes normally have different speeds? The truck lane steams at 90, the fast lane flies at 150. Does "mean" mean the lowest (90) or, indeed, some abstract in-between number? East of Borschov 07:29, 6 August 2010 (UTC)[reply]
