It's all starting to come together.

For years now, "Buy Here, Pay Here" used car lots have been
selling/leasing cars to people with poor credit.

They fit your car with an electronic device that prevents it from
starting unless you punch in a code. The code changes every week;
coincidentally, your paymets are also due once a week, and you don't
get the new code unless you actually make the payment. Some of them
even have embedded GPS receivers and radio transponders to make
repossession easier.

You may also recall the proposal to tax drivers based on the nuber of
miles they drive, rather than on the amount of fuel they buy.

This plan involves fitting cars with another electronic gizmo with an
embedded GPS receiver and radio transponder.

Yesterday I reported on a new scheme whereby insurance companies would
offer discounts (or surcharges) based on actual driving behavior as
monitored by an electronic device in your car that is connected to a
GPS receiver, a cellular radio network, and the local computer network
inside your car that the car's various embedded computer modules use
to exchange information. For the moment, they only relay odometer,
acceleration, and braking data, but the potential is there for much
more.

And, of course we all remember the exciting new Dash Express, a
navigation system which promises real-time traffic data via a two-way
network connection to your car. In exchange for your own telemetry
data, you get an aggregate version of everyone else's telemetry data
which can be used to make routing decisions.

Looks like the Military Industrial Complex that Ike warned us about is
putting all the pieces in place to make all of these things and many
more a reality. Big Government and Big Business have joined forces to
serve their common need: to manipulate and controll the masses. The
carrots offered to entice early adopters will be lower insurance
premiums, the ability to automatically route around traffic
congestion, stolen vehicle recovery, automatic connection to emergency
services when your airbags deploy, electronic toll collection, etc.
etc. That gets their foot in the door - or, rather, it gets their
electronic gizmo into your car.

Once the installed base of tracking devices reaches critical mass,
then the REAL fun will begin.
