from what i've seen on news reports, this is some kind of 'city use' tax for ppl who drive in the larger inner cities (like london, and nyc) created to try to discourage personal use to reduce traffic. this has been proposed for implementation in NYC with london being the model.
supposedly would reduce congestion as the key goal.

or, at least what u mention sounds like this same report.



wow, look where this thread has gone:wtf:
