You cut the wires leading to this transmitter that tells the cops your speed. Problem solved. (Well not this simple, but anything done electronically can also be undone electronically).
This also just applies to any new car sold. I got the impression from the first post that this would have to apply to every car on the road.

the difference is the proposed specification included everything i stated above in the OBD IV system... not in a secondary system such as onstar. that means its and integral part of the ecu, you can't disconnect it.
as far as i know, every car manufactured today, and for the last few years has used an OBD system built into the vehicle (the manufacturer's own system that included a standardized agreement of what OBD must include/exclude).
