We are already there. The London congestion charges are as far as I know
completely based on OCR. The same goes for the congestion charge in
Stockholm. In Stockholm they initially gave out transponders but they
have stopped doing that, probably because the OCR technology is good

I think that the primary reason they are going for systems like that is
that it is much cheaper to install and run than distributing a lot of
transponders or building and staffing toll-booths. The tracking
capabilities is merely an added bonus.

In Göteborg they have a system with cameras which looks at license
plates at different locations and through that measure how long it takes
to drive certain routes. This system is still under construction but
there are some information billboards where they show the current
driving time to various targets. They say that they mask out the last
digit of the plate and destroy the information after a short while, but
who knows.
