That's my interpretation too. If you have an older car that was manufactured without it, you're off the hook.

I think a lot of people are missing the main point here. This isn't necessarily something that's going to be required in the car you drive now.
Yes but the only problem I have with that interpretation is, it looks to me like almost every car currently being made already has it even though it hasn't been officially mandated until now. So I don't see the "years to come" part. It's already there, in new cars being sold today, isn't it?
But think of it as a requirement for cars off the production line in a few years to come.

Because EDRs are not currently required by law, 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 EDR's 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
What is the difference between an EDR and a "black box"?
"EDR" is the term NHTSA has coined to refer to the device commonly installed on motor vehicles to record vehicle technical data for a brief period of time in the event of an accident. In contrast, airplanes, trains and ships use sophisticated recording devices, commonly called black boxes, that record data continuously throughout the operation of the vehicle. They capture much more data than EDRs and, in some cases, can record sound. In commercial aircraft, these are "Flight Data Recorders" and "Cockpit Voice Recorders." An EDR is also referred to variously as a "Motor Vehicle Event Data Recorder (MVEDR)" and "Crash Data Recorder (CDR)."
Different EDR's have different capabilities in what they store. Most passenger vehicle EDR's have the capability of recording the measured deceleration from the crash. Other systems can store up to 5 seconds of pre-crash data including vehicle speed, engine RPM's, percent throttle, brake light switch position, and seat belt switch position.
The U.S. Transportation Department said today it will propose making vehicle "black boxes" mandatory in all vehicles by the end of the year.
The department's National Highway Traffic Safety Administration has long considered whether to make black boxes, officially called event data recorders, or EDRs, mandatory. They collect data about the seconds leading up to a crash and can help investigators determine the cause.
The purpose of the EDR is to record information leading up to an accident, which is meant to assist in determining the cause. GM, Ford Motor Co., Toyota Motor Corp, and Mazda Motor Co. already have the boxes installed on all their vehicles. In 2005, over half the cars released had EDRs on them. Each automaker has set its own specific set of criteria.
When will the EDR unit record data?
For most late model vehicles, data is recorded beginning about 5 to 25 seconds prior to an event or impact that causes the vehicle to experience a change of velocity that exceeds a threshold significant enough to alert the airbag module of the vehicle.
What data is recorded on the EDR unit?
At this time the data that is recorded varies depending on the vehicle manufacturer, make, model and model year. In general it may record data elements like vehicle speed, engine speed (in RPMs), percent throttle, braking status, longitudinal or forward post crash velocity changes, and seat belt usage. By 2011, all vehicles being sold in the United States that collect EDR data, (most models by 2010) will be mandated under federal law to have EDR units that are available for public retrieval, and that are mandated to record a minimum of 15 data elements specified under the law, including those stated above, in events detected by the airbag module, under a standard event detection threshold.
