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:
“It is accordance with our determination to refrain from aggression and build up a sentiment and practice among nations more favorable to peace ... that we have incurred the consent of fourteen important nations to the negotiation of a treaty condemning recourse to war, renouncing it as an instrument of national policy.”
—Calvin Coolidge (1872–1933)
“If you leave your work for one day, you’ll be out of practice for three.”
—Chinese proverb.
“In my practice I’ve seen how people have allowed their humanity to drain away. Only it happens slowly instead of all at once. I didn’t seem to mind.... All of us, a little bit. We harden our hearts. Grow callous. Only when we have to fight to stay human do we realize how precious it is to us, how dear.”
—Daniel Mainwaring (1902–1977)
