Deliverables
• Preliminary project concept plan• Feasibility/ milestones/final presentation for
customer• Product web site operational• Tables (AM and DTC)• Testing data• Prototype 1 (pc version)• Prototype 2 (box)• First units manufactured
36

ODB 3• Sophisticated sensors, monitoring
telemetry and emissions• Fourth Amendment Issues • Uses transmitters to send data to
satellites– Coupled with GPS = gov can find your car– Rat you out! “The specter of having Big Brother in every
engine compartment and driving a vehicle that rats on itself anytime it pollutes is not one that would appeal to many motorists.”
