Practice
Usage of the device varies widely from manufacturer to manufacturer. General Motors and Ford implement the technology on most of their recent models, while Mercedes-Benz and Audi do not use EDRs at all. As of 2003, there were at least 40 million vehicles equipped with the devices. In the UK many police and emergency service vehicles are fitted with a more accurate and detailed version that is produced by one of several independent companies. Both the Metropolitan police and the City of London police are long-term users of EDRs and have used the data recovered after an incident to convict both police officers and members of the public.
Downloading an airbag module in most vehicles is best accomplished by connecting the appropriate scanning tool to the Diagnostic Link Connector (DLC) usually found under the vehicle's dashboard near the driver's knees. The photo to the right shows a DLC download in progress. Alternately, some modules can be downloaded "on the bench" after removal from the vehicle, as shown to the left.
The only system, capable of downloading commercially available crash data in North America, is Bosch Diagnostic's Crash Data Retrieval System.

Famous quotes containing the word practice:
“No exile at the South Pole or on the summit of Mont Blanc separates us more effectively from others than the practice of a hidden vice.”
—Marcel Proust (1871–1922)
“As an example of just how useless these philosophers are for any practice in life there is Socrates himself, the one and only wise man, according to the Delphic Oracle. Whenever he tried to do anything in public he had to break off amid general laughter. While he was philosophizing about clouds and ideas, measuring a flea’s foot and marveling at a midge’s humming, he learned nothing about the affairs of ordinary life.”
—Desiderius Erasmus (c. 1466–1536)
“It is by the goodness of God that in our country we have those three unspeakably precious things: freedom of speech, freedom of conscience, and the prudence never to practice either of them.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
