If we assume for a minute that VW is part of a global conspiracy to crack
down on fun cars (Drivers Not Wanted?), and that they are going to have a
GPS enabled ODBIII in the new cars, they will not be sending anything back
to the GPS sats. If they wanted to invest serious $$$, they could probably
send bursts of compressed data back through a satellite (Iridium) or
cellular communications network. They would have to do a lot of work to get
the data collection stuff set up on their end to handle the influx of
information. Some cars (Cadillac) already have an emergency locator service
for use when you lock your keys out (they can remotely unlock) or for
finding stolen cars.

If they were going to play big brother, they could (as somebody mentioned)
have a EPROM in the car store up data (speed or whatever) for later
retrieval at a deal during servicing.

Yes, the govt can play with the selective availability of the GPS signal to
increase or decrease the accuracy of civilian receivers. Military receivers
can decode the SA signal. The feds say that the usual accuracy with SA on
will be 100 meters or better (*WAY* better than the 1/2 mile figure quoted
earlier). I normally get 30 - 35 meter accuracy and when I have a bunch of
sats locked up, I can get down to 15 meters or so. Special survey grade
differential GPS units can achieve millimeter accuracy.
