The Laws of Physics Trump Traffic Laws
New submitter HeLLFiRe1151 sends this quote from Physics Central:
"Here's a practical application for your physics education: using math to successfully beat a traffic ticket in court. Dmitri Krioukov, a physicist based at the University of California San Diego, did just that to avoid paying a fee for (purportedly) running a stop sign. Krioukov not only proved his innocence, but he also posted a paper detailing his argument online (PDF) on the arXiv server."
The article was posted on April 1. (Need I say any more?) See the discussion on the PhysicsBuzz blog for details.

The Proof of Innocence
Dmitri Krioukov
(Submitted on 1 Apr 2012)
A way to fight your traffic tickets. The paper was awarded a special prize of $400 that the author did not have to pay to the state of California.
If you think this really happened, find a citation for the case that doesn't end up back at this same article.
It turns out that humans are really poor at estimating velocity unless they conform to Newtonian accelerations very closely.. While there has been a lot of research on these issues, I'd like to refer to one of my favorite papers, Sverker Runeson's 1975 paper "Constant velocity — Not perceived as such".

I can tell you as a career prosecutor that usually if you want to challenge something in court you need to make sure you imediately ask the court for a jury trial. Otherwise you won't get common citizens to try your case, but just a Judge who has a working relationship with the officers all the time. Experience shows that if a case is tried to a Judge you are most likely to be found guilty. Sadly I once had a Judge say at the end of a morning in court, "If I think they are not guilty, I give them a lower fine." Juries are always willing to let you off if you can give them any excuse to do so.
In PA if the posted speed limit is LESS than 55 MPH you cannot be cited UNLESS your speed was AT LEAST 10mph over the POSTED limit.
Title 75 - VEHICLES
Chapter 33 - Rules of the Road in General
3368 - Speed timing devices.
(4) No person may be convicted upon evidence obtained
through the use of devices authorized by paragraphs (2) and
(3) unless the speed recorded is six or more miles per hour
in excess of the legal speed limit. Furthermore, no person
may be convicted upon evidence obtained through the use of
devices authorized by paragraph (3) in an area where the
legal speed limit is less than 55 miles per hour if the speed
recorded is less than ten miles per hour in excess of the
legal speed limit.
If they ticket you for 5mph over then FIGHT IT.
Oh, and KNOW THE LAW. LEO is last person on earth who you should place any trust in.
