Proving speed at the time of a car accident

Colin Miller at EvidenceProfBlog excerpts a recent case upholding admission of data from the "event data recorder" on a car. In part:

[T]he vehicle first monitors the two drive wheels to determine the speed of the vehicle....This information is then transmitted to the EDR, and stored in a temporary memory known as a buffer....The buffer continually collects and temporarily stores the last five (5) seconds of data....In the event of an airbag deployment, the EDR writes the information from the buffer to a permanent memory that can be retrieved after a crash....

The National Highway Traffic Safety Administration, who previously studied the use of EDRs and currently employs the technology in their crash investigations, recognizes the utility of this collected data....Furthermore, in 1997, the National Transportation Safety Board recommended that EDRs be installed in all newly manufactured automobiles.
