DF Mariordo has shown patience above  beyond the call of duty and been the epitome of cool over many months in dealing with your incessant attempts over dozens of articles to push a clearly minority POV that any usage charge on congestion emissions or other motoring expense is a tax He has even embraced the inclusion of this minority view in articles albeit in the context of controversy or a minority perspective For each of your popular press articles cited we could pull out many many more that refer to them as charges levies etc  I noted that many of your Ozzie reference articles also used other terms than tax In technical literature you wont find such terminology For your future guidance I again ask you to take a look at a definition of tax such as Chambers or OED Note they use the term compulsory contribution A pure Treasury fundraising tax is compulsory yet these traffic charges can be avoided by changing behaviour by changing fuels routes vehicle class or mode
