To help those who might have a problem understanding what NewsW is
saying...look at any USA major highway/freeway
Look for the diamond saw cut slots (older were square with the corners
cut, or the new ones which are circular), or the RF antenna on over
head signs or poles. There will then be a digital camera mounted on
a pole about 50ft high.
They are flux field sensors, those slots on the pavement. Always two
of them so they will know direction, time of day and the biggie speed
Originally as sensors for smart stop lights to tell the computer that
there is a vehicle. But that is for stationary systems...why on the
highway/freeway?
The RF antennas sense even more information.
And soon, as NewsW says, they can scan what the vehicle computer is
telling you in real time.
Marry that with RFID's in your clothes, wallet (credit cards now have
them embedded), your vehicle computer, etc. What is that you say???
Well when someone with an RFID set of plastic cards in their wallet
(that includes your drivers license)...the vehicle computer will/can
capture all that info.
When it is told to tell by one of those RF antenna...it will broad cast
and tell that XYZ drivers license is 'still' in the vehicle, as are
these other licenses, VIN, etc.
It will also tell what the computer is programed to tell and this is
where the programers most likely will modify...but...the computers
memory is now very large and most likely nonvolatile ROM of some sort
Maybe strain gauges some day and do you know what that means? Look at
the rolling weigh stations where they can weigh semi's without them
having to come in and stop on the scales. They can weigh them while
they are rolling in the slow lane out there on the highway
Basically the cost of that type of system and instrumentation is low
enough to allow the OEMs to install them

Takes ten minutes to plug in a laptop & switch to the "emission test" program. When that's done, just put the "emission junk bypass" program back in until next year.
You will really like OBD III:
http://lobby.la.psu.edu/_107th/093_OBD_Service_Info/Organizational_Statements/SEMA/SEMA_OBD_frequent_questions.htm
"WHAT IS OBD-III?
A program to minimize the delay between detection of an emissions malfunction by the OBD-II system and repair of the vehicle
Two basic elements:
Read stored OBD-II information from in-use vehicles.
Direct owners of vehicles with fault codes to make immediate repairs
OBD-III TECHNOLOGIES
Three ways to send/receive data:
Roadside reader
Local station network
Satellite
ENFORCEMENT MECHANISMS
Incorporate into biennial I/M program
Read fault code to screen for vehicles that need complete testing
Pass or short test for vehicles with no fault code
Does not speed up repair process
Out-of-cycle inspection
Compile and screen data
Mail notice to vehicle owner requiring out-of-cycle inspection within 10 days
Require Certificate of Compliance (C of C) on next registration/resale, or
Require C of C within 30-60 days, with citation for noncompliance
Enforce citation via court and/or DMV penalty at next registration
Roadside Pullover
CHP flags down vehicles with fault codes
Technician verifies problem by inspecting and/or testing vehicle
Issuance of notice requiring out-of-cycle inspection
Same enforcement (C of C /citation) "
