How prey, do they propose to enforce the use of satellite and / or
cellular
phone tracker systems for cars ?

This is a madly expensive way to TRY to solve congestion in relatively
small
number of places.
And, as with petrol, people will just pay what it takes to go where they
want to go and when they want to go.
Congestion is self defeating anyway, so unless you build more roads, you
may
as well do nothing !
It would be much better to concentrate of keeping the traffic moving, sort
of stand Livingstone on his stupid head....

Congestion charging is about keeping the traffic moving though. You remove
about 10% of the traffic by pricing it out, and then the traffic can move,
road capacity increases, and journey times drop ~30%
