In the UK, motorists that want to park are in many places forced to choose between one kind of oppression and another.

In some places, they are required to pay through a snoop-phone. That is unjust because it identifies them, and makes them run nonfree software.

In others, they are charged for parking by a system that recognizes car license plates. That spares them the nonfree software, but it is unjust because it identifies them,

There should be a law requiring all charged parking spaces to allow cash payment and not record who parked there.
