NHTSA has withdrawn this first-porposed-in-2012 requirement b/c manufacturers are already doing it.
SEMA summary:
By Washington, D.C., Staff
The National Highway Traffic Safety Administration (NHTSA) has withdrawn a proposed rule to require event data recorders (EDR) in all new cars and trucks since they are already being voluntarily installed by automakers in nearly all light-duty vehicles.
NHTSA had proposed the rule in 2012 when many vehicles did not have so-called black boxes. NHTSA already has a standard for performance requirements for EDRs, 49 CFR Part 563. Data collected can identify pre-crash vehicle speed and whether brakes were applied and air bags deployed.
A 2015 law requires NHTSA to consider updating the pre-crash data being collected.
So I looked it up NHTSA 49 CFR 563 to see what NHTSA would have required and that OEMs are already doing ... a lot more than I thought would be included!!
NHTSA 49 CFR 563 to see what measurements would be recorded (:faint:) -- you can almost divine the highly-technical battle-of-the-experts scenarios that will be happening in courts throughout the land for everything from severe accidents and homicides to DWI defenses and virtually any physical damage to a human being beyond bruises or property damage beyond destroyed picket fences :doh:
This does seem like overkill, but the information is already there and what is recorded is already subpoena-able so I guess it was inevitable to make it all recorded and in a standardized way. Sort of scary!
